January 2024 – A Brief History of the Bass Guitar

by Tony Drew | posted in: History, Introduction, Observations, Opinion | 0

Prelude

WELCOME FAIR MUSIC‑MINDED PATRONS to the first CRAVE Guitars’ monthly article of the New Year. While we may be less than a full month into the year Two Thousand and Twenty Four of the Common Era, one hopes it is off to a good start despite global uncertainty (and insanity). Let us hope that those intent on geopolitical conflict come to their senses, unlikely as it may seem, rather than escalate tensions further. I don’t know about you but I don’t want to be part of the doomsday generation. Scary.

“Bellum omnium contra omnes (the war of all against all)” – Thomas Hobbes (1588‑1679)

Getting back to the musical point, ask pretty much anyone with a slight interest in modern music culture, the question, “Who invented the first bass guitar?” and I’m sure a lot of people would say, “Leo Fender, of course”. Well yes… and no. In the world of vintage guitars, things are rarely quite as straightforward as one may at first think.

With the recent addition of CRAVE Basses to the CRAVE Guitars, Amps and Effects family, this month seems perfectly apt to take a quick look at how the electric bass guitar as we know it came into being and how it has become such an integral component of contemporary music.

Primarily as a guitarist, my dalliances with bass guitars up to now have, I admit, been spawned out of curiosity and exploration, rather than a serious preoccupation. Those dalliances, though, span well over four decades, so the bass encounter isn’t a single, short or recent ‘event’.

We do not start the story, as many might imagine in the 1950s. We’ll come back to that in a little while. Before we get there, though, we should go back quite a few years. Many, many years in fact, starting with the classical orchestral double bass, originating from the 15^th Century or thereabouts. Then we’ll explore the modern‑day innovations starting in the 1920s and 1930s before the ‘big bang’ that really exploded in the 1950s and 1960s. Finally we’ll come up‑to‑date, with a look at the instruments, equipment, artists and sounds that have helped to shape the modern musical landscape. Finally, we’ll take a wee peak into the near future of bass instruments.

The fretless acoustic double bass

Before the solid body fretted electric bass guitar, popular music relied almost totally on the acoustic upright double bass for low frequency impact. The instrument’s origins date approximately to the 15^th‑16^th Century in Venice, Italy. Venetian musician, Silvestro Ganassi developed a ‘bass viola da gamba’ in 1542, widely regarded as the forerunner of today’s double bass. It wasn’t until around 1700, though, that the double bass became part of the opera orchestra. The double bass as we now know it is the largest and lowest‑pitched chordophone in the classical music orchestra.

As a quick recap, defined by the Hornbostel‑Sachs system of musical instrument classification, a chordophone is a musical instrument that makes sound from vibrating one or more taught strings by bowing, plucking or striking the strings. Examples of chordophone types include violins, guitars, and pianos respectively. The word chordophone stems from the Greek words for string (chordē) and sound (phonē).

For more on the historical origins of musical instrument classification (to provide a context for the development of the guitar), see CRAVE Guitars’ March 2018 article.

The traditional 4‑string double bass is usually played in one of two ways, either by rubbing the strings with a bow (arco) or by plucking the strings with fingers (pizzicato). Some modern double bass players, for instance in rock & roll and rockabilly, also use a distinctive ‘slap’ technique. This percussive sound derived from the ‘Bartók pizzicato’ (‘snap’ pizzicato) named after the Hungarian composer and pianist Béla Bartók.

Depending on the style of music, the double bass is also known by a number of other names, all of which refer to the same instrument. Some of these alternative monikers include bass, upright bass, string bass, acoustic bass, acoustic string bass, contrabass, contrabass viol, bass viol, bass violin, stand‑up bass, bull fiddle, doghouse bass and bass fiddle.

The traditional double bass is a large acoustic fretless instrument of the violin family that is played upright. The deep, resonant, woody tone of the double bass endows it with a very different sound when compared to the modern solid body fretted electric bass guitar. The tuning of the double bass is different from other members of the orchestral sting instruments, in that it is tuned in fourths (E‑A‑D‑G) rather than a violin’s fifths (G‑D‑A‑E). The double bass, then, is tuned the same as a modern bass guitar, an octave below the bottom four strings of a 6‑string guitar in standard tuning. This particular characteristic aided the bass’s transition from classical to modern day musical styles.

Originally, double basses were more likely to have three strings until four strings became commonplace by the 19^th Century, by which time the standard format and construction of the double bass had become established. There are, however, 5 and 6 (or more) string variants and there are also various alternative tunings.

The double bass has been the mainstay of orchestral string sections and chamber music for several centuries in one form or another. It was predictable that, with the emergence and evolution of the major modern popular music genres, such as jazz, blues and country & western that the double bass would become the go‑to bass instrument, at least up until the 1960s when the solid body fretted electric bass guitar became predominant. However, the double bass hasn’t disappeared from contemporary music completely. Plenty of present‑day artists still use or revert back to the double bass for authenticity and/or effect.

The main drawback experienced by many players is that the double bass is a substantial piece of equipment. The full‑size double bass is almost 75 inches (190cm) tall, weighing in at c.20‑25lbs (9‑11½kg), without its hefty case. The scale length is set at around 42” (107cm), much longer than most modern bass guitars. Given these dimensions, the double bass is sizeable, cumbersome, unwieldy and plain heavy, making it far from the easiest of instruments to move around or play. There are smaller double basses including ¾, ½ and ¼ size, mainly aimed at younger players. Even so, the double bass not for the faint hearted, as the smallest ¼ size instrument is still over 61” (156cm) tall.

Another drawback is the double bass’s acoustic construction. Like the acoustic guitar, in the first half of the 20^th Century, the acoustic double bass’s lack of volume made it hard to be heard in a jazz‑era big band mix unless there was some form of electrification through either a magnetic pickup or a microphone connected to an amplifier and, even then, acoustic instruments can be prone to feedback in high sound pressure level environments.

Traditional double basses are not only large but, because of their construction, they are also quite expensive, making them a major investment and therefore difficult for novices or younger players to access and learn.

Even so, despite its limitations, during the 20^th Century the double bass became widely used in a diverse range of modern music genres, including jazz, blues, swing, rock & roll, rockabilly, country & western, bluegrass, folk, funk, reggae, metal, rock, pop, tango and visual media soundtracks.

Trivia: Believe it or not, there is an even larger bass, first built c.1850 by the French luthier Jean‑Baptiste Vuillaume (1798‑1875) in Paris. The octobass, as it is called, has three strings and is basically a larger version of the double bass tuned a further octave down. The octobass is a truly gargantuan beast, approximately 137” high (348cm).

The electric upright bass

To enable modern players to experience the spirit of the acoustic double bass in a more convenient and amplified form, there is the modern Electric Upright Bass (EUB), which is also played, as its name suggests, upright, like a traditional double bass.

EUBs allow for greater portability while retaining the playing style and general sound of its forebear. As the EUB doesn’t require the substantial acoustic resonating chamber of a double bass, they often feature a ‘skeleton’ body, making it much smaller, lighter and cheaper to produce. The minimal structure may have either a solid body or a small acoustic body.

A magnetic, piezo or condenser bass pickup provides the means to route the signal via a bass amplifier to loudspeakers. Like a double bass, the EUB’s strings can be bowed or plucked, although that is dependent on fingerboard and bridge radius. While evoking its acoustic origins, the structural and electric characteristics of the EUB endow it with a unique sound all of its own.

As the EUB’s construction isn’t bound by convention like its orchestral sibling, the flexible format allows for a range of scale lengths to be employed from around 30” (76cm), through 34” (86cm) like a long scale bass guitar to the full 42” (107cm) of a double bass, making it much more accessible to a range of players. Almost all EUB necks allow for a full two‑octave range and most but not all are fretless. Compared to the double bass or the electric bass guitar, the electric upright bass tends to be a modern, notable but relatively niche instrument. There are EUB models at all price points, making it easier for novices and experienced players alike.

The first production electric upright basses were developed independently in the mid‑1930s by Regal (Electrified Double Bass), Vega (Electric Bass Viol), Rickenbacker (Electro Bass‑Viol) and Audiovox (bull fiddle – see below). Gibson introduced their special order Electric Bass Guitar in 1938, which was still an upright fretless instrument with a hollow body and a magnetic pickup.

Manufacturers of electric upright basses include Framus, Ampeg, Warwick, Ibanez, Yamaha, Palatino, NS Design (Ned Steinberger), and Harley Benton.

The first solid‑body fretted electric bass guitar

As hinted at above, while Leo Fender was the major innovator associated with the solid‑body fretted electric bass guitar, he wasn’t the first. He was beaten to the starting post by at least some 15 years. Hardly a photo finish!

The first indication of the possible future of a bass guitar was in 1924 when the legendary Gibson designer, Lloyd Loar came up with a prototype electric bass. The Loar concept focused on the body, pickup and strings but with little additional detail. Loar’s radical design was rejected by Gibson management at the time. Loar left Gibson shortly thereafter in 1924, so his visionary ideas for an electric bass guitar went no further.

Nearly a decade later, around 1933, American musician and inventor Paul H. ‘Bud’ Tutmarc (1896‑1972), based in Seattle, Washington, began experimenting with reducing the size of the double bass to a more manageable instrument. Tutmarc originally devised an electrified fretless double bass‑style instrument described as an electric 4‑string upright ‘bull fiddle’, slightly smaller than a cello.

It’s worth a quick diversion to go back in time to take in an original report from the ‘Seattle Post‑Intelligencer’ newspaper, which published the story on 17 February 1935. The headline read, “Pity Him No More – New Type Bull Fiddle Devised.”

The article went on to state that, “People have always pitied the poor bass-fiddler… who has to lug his big bull-fiddle home through the dark streets after the theatre closes. But he doesn’t have to do it anymore. Because Paul Tutmarc, Seattle music teacher and KOMO radio artist, has invented an electric bull-fiddle. One you can carry under your arm. And it doesn’t even need a bow, either. You pluck a string – and out of the electric amplifier comes a rich, deep tone, sustained as if five or six bass violinists were bowing five or six bass‑violins with masterly artistry. The tone is sustained as long as you want it, too, without a bow.” The instrument described in the article was a cello‑like upright fretless instrument with an electromagnetic pickup.

Tutmarc was, however, about to do something far more radical. By 1935-1936, Tutmarc, had changed direction and developed the first solid body fretted electric bass guitar, pretty much recognisable in its modern form. It was this version of Tutmarc’s bass that was intended to be played horizontally, rather than upright, in a similar way to the modern bass guitar. The 1935 sales catalogue for Tutmarc’s company Audiovox featured his ‘Model 736 Bass Fiddle’, a solid‑bodied electric bass guitar with four strings, a fretted neck, with a 30½” (775mm) scale length, an ebony (or purpleheart) fingerboard with 16 frets, a black walnut body, a hidden single Tutmarc‑Stimpson horseshoe pickup below a mirror-steel faceplate, and a single volume control.

In addition, as an electric bass guitar would be pretty much useless without the means to amplify the sound, Audiovox also sold an accompanying ‘Model 936’ bass amplifier with 18 watts of power and a 12” Jensen Concert speaker.

Around 100 of the Model 736 Audiovox bass guitars were made in the mid‑1930s. However, there are only thought to be three Model 736 Tutmarc bass guitars still in existence today, making them remarkably rare. One belongs to the Experience Music Project (EMP), now known as The Museum of Pop Culture (MoPOP), a non‑profit enterprise founded by Microsoft co‑founder Paul Allen in 2000 and based in Seattle, Washington state, USA. In 2018, a 1936 Audiovox Model 736 bass guitar was reportedly sold by Tutmarc’s grandson on eBay for $23,850.

Sadly, for Tutmarc, the Audiovox 736 was not a commercial success. The price tag was high for the mid‑1930s, in a country still severely affected by The Great Depression (1929‑1939). The 736 bass fiddle originally cost $65 and the matching 936 bass amplifier cost $75, placing it well out of reach for many musicians. The high price and the radical concept didn’t attract enough musicians at the time and it wasn’t long before it was discontinued and was subsequently forlornly forgotten to history. Tutmarc’s company, Audiovox folded in 1950.

It can well be argued that Tutmarc was ahead of his time. Perhaps it is a case of supply looking for a demand that consumers didn’t know they needed. Maybe it was bad timing and/or bad luck. The Model 736 also arrived shortly before the outbreak of World War II when the guitar manufacturing industry was deemed ‘non‑essential’ and resources were diverted to the American war effort. Furthermore, a bass guitar didn’t seem to fit seamlessly into any of the prevailing musical styles at that time.

It is surprising, though, that such a significant innovation in guitar history isn’t more widely known about. Perhaps it is time, nay overdue, for Tutmarc’s milestone achievements to be deservedly recognised.

One company, Luthiery Laboratories, makes modern‑day replicas of the Audiovox 736, keeping the spirit of the original instrument alive.

The first commercially successful mass produced solid body fretted electric bass guitar

And so it was that the scene was set for someone else to step in and make the bass guitar ‘a thing’. That someone else was Clarence Leonidas Fender (1909‑1991). Unlike poor old Paul H. Tutmarc, you may just have heard of him.

A Potted History of the Guitar Part VI (1950s and 1960s):

Once the proverbial ball started rolling, the bass guitar had a phenomenal, transformative and relatively rapid impact on modern music that cannot be underestimated or understated. It is also very easy to take the electric bass guitar’s presence on stages, in studios and bedrooms all around the world for granted. Back in 1950, though, no‑one other than a select few in Fullerton, California had any idea of what was to come.

So… what are we actually talking about? The answer, after the lengthy preamble (apologies for keeping you on tenterhooks for so long), is the mighty Fender Precision Bass. Three little words. Game changing, era defining and well‑deserving of all the hyperbole attached to it over the past seven‑plus decades. So much has been written about the Precision that there is little need to dredge up the detail again, so what follows is a brief overview.

Leo Fender was working on a prototype back in 1950, bringing the world’s first commercially successful mass‑produced electric bass guitar to market in 1951. Fender designed the Precision Bass (often shortened these days to P‑Bass) to overcome the many drawbacks of the acoustic double bass alluded to earlier in this article. Even the name, Precision, referred to the fretted neck to enable musicians to play in tune far more precisely than on the double bass’s fretless neck. Conservative double bass players may well have looked at the Precision Bass in the same way that conservative guitarists looked at the Fender Telecaster, which had been introduced a year earlier in 1950. Consternation and indignation were probably natural initial reactions from the ‘old‑school’.

At its most basic, the Fender Precision Bass is a solid body, 4‑string bass guitar equipped with a single pickup and a one‑piece 20‑fret maple neck with rosewood or maple fingerboard. It all sounds so very straightforward and unremarkable nowadays doesn’t it?

The Precision Bass didn’t, however, appear fully formed. The original design of the Precision borrowed several design features from the Telecaster guitar, other than the double cutaway body. Initial models carried one single coil pickup, a slab body, large scratchplate and a Tele‑like headstock.

After Fender introduced the Stratocaster guitar in 1954, some of its design features were brought over to the Precision including a contoured body and a Strat‑like headstock. The original pickup was replaced with a single split coil hum cancelling staggered design and a sleeker redesigned scratchplate. It is this version of the Precision from 1957 that has stayed in production largely unchanged to the current day. There have been many, many variants with numerous changes in specification over the years, including a fretless version (ironically, given the origin and intention of the Precision’s name). 5‑string versions, 22‑fret necks, active electronics, multiple pickups, etc. followed.

The original pre‑1957 Precision design has been re-issued by Fender at times over the years, often called the Telecaster Bass to differentiate it from the post‑1957 Precision specification.

The popularity of the Fender Precision Bass grew significantly throughout the 1950s especially with rock & roll and country fraternities, as well as with session musicians. During the 1960s the solid body fretted electric bass guitar became dominant in most modern musical genres. During the early days, there wasn’t a great deal of choice in terms of alternatives to the Precision but that was to change later on.

Fender capitalised on their supremacy by introducing the solid body fretted electric Fender Jazz Bass in 1960 (originally called the ‘Deluxe Model’). The svelte Fender Jazz Bass (often now shortened to J‑Bass) was designed to appeal to a different customer base. Like the offset bodied Fender Jazzmaster guitar, it was aimed squarely at the dyed‑in‑the‑wool jazz community. However, like the Jazzmaster, the Jazz Bass’s appeal spread far wider than jazz musicians. Like the Precision, the Jazz Bass has rightly become an iconic industry standard solid body electric bass guitar.

Throughout the years, both the Precision and Jazz Bass have featured sizeable chrome covers over the pickup and the bridge, despite these items limiting playing techniques such as palm muting the strings. As the covers are purely aesthetic, rather than functional components, it is fair to say that the vast majority of musicians removed these covers permanently.

Without doubt, the Fender Precision Bass and its younger sibling the Jazz Bass are icons of contemporary music and remain hugely popular today. Consumers can purchase genuine P‑Bass and J‑Bass models from the budget Fender‑owned offshore‑produced Squier brand, through Mexican and American‑made Fender models, to the high‑end Fender Custom Shop versions. Throughout the decades, the Precision and Jazz Bass models have oft been imitated and/or blatantly copied by other manufacturers, eager to cash in on Fender’s industry‑dominant status.

Understandably, over the years, the Precision and Jazz Bass have become highly collectable, especially the earliest models. The highest vintage market prices undoubtedly belong to the models from 1951 (Precision) and 1960 (Jazz Bass) to 1965, when Leo Fender sold his company to industry giant CBS. Fender equipment from this period is known as ‘pre‑CBS’.

For more information on the Fender Precision and Jazz Bass, just complete any Internet browser search and, alongside a great deal of drivel, there is a massive volume of fact and opinion available, often described in forensic detail.

Evolution of the electric bass guitar

It is probably fair to say that, since 1951 and the introduction of the Fender Precision Bass, other brands were in the position of having to play catch up. In particular, Fender’s biggest competitor, Gibson, was wrong‑footed and they have never been able to compete on a level playing field. In 1953, Gibson released the EB‑1, which was a violin‑shaped solid mahogany body bass with a set neck. The EB‑1 didn’t catch on and was replaced by the semi‑acoustic ES‑335‑shaped EB‑2 in 1958, the SG‑shaped Gibson EB‑0 in 1959 and the EB‑3 (made famous by Jack Bruce of Cream) in 1961. While the semi‑acoustic EB‑2 proved popular, its Epiphone‑branded counterpart, the Epiphone Rivoli proved more successful. All these early Gibson basses used a shorter 30½” scale. In 1959, Gibson also released a hollow body EB‑6 6‑string bass.

Possibly Gibson’s best contender for an iconic bass guitar is the Gibson Thunderbird, originally introduced in 1963. The Thunderbird was based on Gibson’s Firebird guitar, designed by legendary American car designer Raymond Dietrich (1894‑1980). The Thunderbird was the first Gibson solid body bass to use the 34” scale made popular by Fender. Like the Firebird, the Thunderbird was redesigned in a simpler ‘non‑reverse’ form for 1966 and the original ‘reverse’ shape wasn’t reissued until the mid‑1970s. During the 1970s, Gibson also released the Ripper and Grabber basses but neither really captured bass players’ imaginations (or their precious dollars!). Later additions like the Gibson Triumph, Victory and RD basses didn’t fare much better as viable competition for Fender’s stalwarts. Epiphone have Thunderbird and EB basses in their line‑up alongside Epiphone‑specific basses such as the Newport and the Embassy.

Over at Danelectro in Neptune, New Jersey, Nathan Daniel launched the world’s first 6‑string bass, the UB‑2 in 1956 comprising a single cutaway semi‑hollow bass with a 30” scale, 24 frets and dual single coil pickups, earning its nickname the ‘Tic Tac bass’. In 1958, Danelectro replaced the UB‑2 with two new 6‑string bass models. The first was the Long Horn 4623 bass with a radical new lyre‑like design 24 frets, and a short 25” scale. The other was the Short Horn 3612 with stubby double cutaways, 29½”scale and only 15 frets. All Danelectro models substantially undercut the retail prices of both Fender and Gibson’s basses. The 6‑string models seemed to attract guitarists rather than bass players to their designs, providing a novel bridge between guitar and bass camps.

It should be noted at this point that older 6‑string basses are generally tuned an octave below a guitar in standard tuning, to E-E, while the baritone guitars that were appearing at the time were tuned either to B‑B or A‑A. On the other hand, modern 5‑string basses simply add a lower B string while modern 6‑string basses tend to add lower B and higher C strings compared to an equivalent 4‑string bass. Confused?

Meanwhile, back in the 1960s, Fender weren’t resting on their laurels. Following the popularity of the ‘student’ Mustang guitar, Fender introduced the short scale Mustang Bass in 1966. The Mustang Bass spawned two later variants, the Bronco Bass (introduced in 1967) and the Musicmaster Bass (introduced in 1971). Fender also released two esoteric ‘bass’ guitars, the Fender Bass V (introduced in 1965), which was the world’s first 5‑string bass guitar and the 6‑string Bass VI (introduced in 1961). The latter was strongly influenced by the Fender Jaguar guitar design. The Bass VI was Fender’s upmarket response to the Danelectro 6‑string bass introduced 5 years earlier. The Bass VI is unique in having 3 pickups, 6 lighter gauge strings, a short 30” scale, a floating bridge and a mechanical vibrato as used on the Jazzmaster/Jaguar guitars, as well as a removable string mute. To compete with the Gibson EB‑2 and Epiphone Rivoli thinline semi‑acoustic basses, Fender introduced the hollow Coronado Bass in 1966.

In addition, the ‘other’ Californian company, Rickenbacker, run by F.C. Hall at the time, also wasn’t going to be left on the side‑lines in the bass department. Rickenbacker had hired Roger Rossmeisl (1927‑1979) who designed the brand’s key guitars and the 4000 series basses. The Rickenbacker 4000 bass with its distinctive cresting wave body outline and thru‑neck construction was launched in 1957. Subsequent models were named 4001, 4002, 4003, 4004, all being variants of the same basic instrument. There isn’t enough space to go into the specification differences here.

A decade after Leo Fender left the company that still carries his name today, Music Man was formed in California and released Leo Fender’s vision for the next evolution of his era defining bass guitars. The Music Man Stingray Bass was released in 1976 with a single large bridge humbucker, distinctive 3+1 headstock, innovative on‑board active electronics and an integral string mute. While Music Man’s guitars never caught on at the time, the Stingray Bass has joined Fender and Rickenbacker as an iconic design for many bass musicians. The Stingray Bass was especially popular for funk slap‑style bass technique for the likes of Louis Johnson of the Brothers Johnson.

There are a few other notable basses, such as the German Höfner ‘violin bass’, the 500/1, made famous by Paul McCartney of The Beatles. This model, introduced in 1955, with its carved solid spruce top and humbucking pickups, is often nicknamed the ‘Beatle Bass’. Beyond the Beatles connection, though, the 500/1 remains a relatively minor entry in the bass stakes, while the company’s only other notable entry being the Höfner Club and Verythin basses.

Another oddity to mention at this point is the Swedish Hagström H8, unique for being the world’s first mass‑produced 8‑string bass, with four pairs of strings on a short 30” scale. The H8 was only produced briefly from 1967‑1969.

Throughout the 1960s, 1970s and 1980s a plethora of other companies jumped on the bandwagon, eager to make the most of the massive increase in demand as rock, pop and other genres proliferated. Many of the basses produced during this time were flagrant facsimiles of the best‑selling American brand models, often by Japanese companies (now termed ‘lawsuit‑era’ copies). Other companies like Warwick in Germany were making their own headway with their successful original‑design Thumb and Streamer basses.

Today (2024), Fender arguably still rules the roost with basses covering all bases (sic!) from budget to elite models. All other brands stand firmly in Fender’s enviable shadow. While Fender may dominate, there are now plenty of alternative options. There are some incredible bass guitars out there, some of which are listed later in this article for those that want to diverge from the predictable industry standard ‘Fender sound’. There are numerous ways to deviate from the common path, with different brands, string/pickup configurations, electronics, scale lengths, body construction, etc. The quality of budget instruments is vastly superior to anything available in the past and provides a strong basis (again, sic!) for players seeking to learn and develop their skills.

The acoustic bass guitar

While the solid body electric bass guitar finally took the world by storm from the 1950s and 1960s, the acoustic bass guitar has proved to be another modern, notable and niche instrument. The first (largely unsuccessful) attempts at acoustic bass guitars began to appear in the 1950s as a logical extension to its electric counterpart.

Historically, one of the earliest acoustic bass‑like instruments was the Mexican guitarrón, which has its roots in the 16^th Century and is widely used in Mexican Mariachi bands. While looking similar to a guitar, these huge instruments were either 6‑string or 12‑string acoustic instruments, tuned in A‑D‑G‑C‑E‑A.

In 1972, Ernie Ball introduced the Earthwood acoustic bass guitar, stating that “…if there were electric bass guitars to go with electric guitars then you ought to have acoustic basses to go with acoustic guitars.” A simple yet ‘blindingly obvious’ observation, given the benefit of hindsight. Ernie Ball took a guitarrón, being the nearest thing to an existing acoustic bass guitar, and created a more practical instrument for guitar‑centric American consumers. The Earthwood was relatively short‑lived but the foundation of the acoustic bass guitar was established. American company Washburn took the concept and created more successful instruments that coincided neatly with MTV’s Unplugged concert series (1989‑1999). Interestingly, despite starting it all, Ernie Ball does not have an acoustic bass guitar available to buy at the time of writing.

Acoustic bass guitar construction is essentially similar to the steel‑strung flat top acoustic folk guitar, with a larger hollow wooden body and a longer scale neck. Most acoustic basses have four strings, tuned in the same way as an electric bass, E‑A‑D‑G, an octave below a standard guitar. The majority of acoustic basses have fretted fingerboards, although some are fretless.

Like many modern day acoustic guitars, many acoustic bass models have pickups to enable them to be amplified for stage use or DI’d for recording purposes. Some instruments are thinline electric semi‑acoustic basses while others are full‑depth electro‑acoustic basses. These are designed primarily as acoustic basses with an on‑board pickup for additional amplification when needed.

Today, there are any number of acoustic bass guitars on the market for every level of player and every price point from many key manufacturers including, amongst others; Martin, Taylor, Guild, Fender, Takamine, Ovation, Tanglewood, Epiphone, Warwick, Epiphone, Washburn, Godin, ESP, Breedlove, Larivée, Framus, Hohner, Ozark, Dean, D’Angelico, Ibanez, Sigma, Alvarez and Cort.

Bass guitar amplification

In the early days of bass guitars, brands released bass amplifiers to accompany their instruments, often sold as a package (see Tutmarc’s Audiovox above, for example). Other brands like Rickenbacker did the same in the early days. The main difference between guitar amps and bass amps is that the latter are tuned specifically to reproduce bass frequencies accurately. A standard 4‑string bass guitar produces low frequencies in the range 41Hz to 100Hz with overtones extending up to 4‑5kHz (not dissimilar to an acoustic double bass in fact).

In terms of sound pressure levels, bass frequencies need more power to be heard by the human ear/brain at the same volume as higher frequencies, so bass amps tend to have higher power ratings than guitar amps. In the past, speakers for bass also tended to be larger with 12”, 15” or even 18” to shift the amount of air needed at lower frequencies. In contrast, guitar speakers tended to be 10”or 12”. Bass speaker cabinets, especially those with multiple speakers, normally had sealed or ported enclosures to increase volume. For all these reasons bass amplifiers and speaker cabinets tend to be different to their guitar equivalents.

Probably the most famous brand associated specifically for its bass amplification is the American company Ampeg, founded in 1946 and now under the ownership of Japanese giant, Yamaha. Ampeg started out attempting to amplify the acoustic double bass in 1949 by using a microphone/pickup in the instrument’s stand. The ‘Amplified Peg’ as it was called was then shortened to ‘Ampeg’ and the rest, as they say, is history. Their most famous range of amps was the 300W Ampeg SVT from 1969 and their bass combo amps, the B‑15 from 1960, as used by the likes of Motown session bass player James Jamerson.

It was no surprise that Fender, the leader in the world of bass guitars from the 1950s should also produce bass amps/cabs. Perhaps the most famous Fender bass amp was the Bassman from 1952 onwards, first introduced as a combo valve amp with a 15” speaker. The most desirable though, was the Dual Rectifier Bassman valve combo with 4×10” speakers. From 1960. Fender also released a ‘piggy back’ amp head and speaker cabinet design to cope with higher power levels and to provide flexibility. From 2000, Fender released a solid state version of the legendary Bassman amp. The original valve Bassman also became beloved by many guitar players for its tone, for instance by the late blues rock guitarist, Stevie Ray Vaughan (SRV).

Student bass players also needed a bass amp. So Fender introduced the Musicmaster Bass amplifier in 1970, as a companion to the Fender Musicmaster Bass guitar. The Musicmaster Bass combo amp was a very simple affair with one channel, 12W of power, volume and tone controls and a single 12″ Fender speaker. Like the Bassman, it has latterly been enjoying a bit of a revival as a budget vintage amp for guitarists. The Musicmaster Bass amp was discontinued in 1982 after the introduction of the Fender Studio Bass combo and Japanese Fender Sidekick Bass 30. Nowadays, the extensive Fender Rumble series has proved very popular with bass players.

Legendary British amplifier company Marshall was not going to be left behind. Marshall’s first 100‑watt bass head was the JTM 45/100 / JTM 45 Super 100 model. Another, also dating from the second half of the 1960s, is the JMP #1992 Super Bass 100 (100W) and JMP #1986 Bass (50W). Like the Fender Bassman, the Marshall Super Bass 100W also proved popular with guitarists. Bass players were also known to use the Marshall #1963 Super PA (50W) and Marshall #1968 Super PA (100W) amps.

Another legendary British amplifier company, VOX produced bass versions of its AC‑15 and AC‑30 combo amps. These were followed in 1963 by the VOX T‑60 and Foundation amps, the latter promoted by Bill Wyman of the Rolling Stones.

German acoustic amp company AER also produce a range of bass amps, particularly well‑suited to amplifying acoustic and electro‑acoustic bass guitars.

Bass guitarists turn out to be a little less conservative than their guitarist counterparts, especially when it comes to amplification and speaker cabinets. For instance there are plenty of modern‑day bass amps that use efficient solid state D‑class amplification (a type of amplifier that uses digital switching technology to amplify audio signals efficiently), with very high power ratings – 500W and 600W or more being not uncommon. Bass amps often also make wide use of sophisticated on‑board EQ. Speaker cabinet configurations also tend to be more versatile with reflex ports, horns, tweeters and combining multiple speaker types being common.

There are many other valve, solid state or hybrid bass amplifier manufacturers not mentioned above, including Trace Elliot, Ashdown Engineering, Mesa/Boogie, Peavey, Music Man, Hiwatt, Laney, Sound City, H/H, WEM, Hartke and Orange.

Bass guitar effects

Things have changed a great deal over the decades since 1951. In the early days of the solid body electric bass guitar, most players plugged straight into their amps without much in the way of tone augmentation.

By the 1970s and 1980s bass players had a paucity of effects specially designed for their instruments, so they generally adopted guitar effects with just a few bass‑specific pedals to choose from. Since the industry started to migrate to digital technology from the 1980s onwards, the major effect companies began to produce pedals designed primarily for use with bass guitars. Now, in the 2020s, there is plenty of choice with most of the big players in the effect industry now making bass‑specific effect pedals, including Electro‑Harmonix, MXR, BOSS, Ibanez, Fender, Laney and Ampeg.

In addition, from around the start of the new millennium, a number of manufacturers turned their ideas for integrated multi‑effect units into practical musicians’ tools that became popular for both guitar and bass, including BOSS, VOX, Zoom, Tech 21, Behringer and Valeton.

In 1998, Line 6 introduced a ground‑breaking innovation called the POD, which put many guitar effects, amps and cabinet emulations into a single portable unit. While the little red kidney shaped POD was initially directed at guitarists, the rack mounted Line 6 POD Pro models came in both guitar and bass versions. Since then, Line 6 and other manufacturers now combine guitar and bass amp/effect/cabinet emulations into a single unit. These units are constantly improving and are gradually replacing stage backlines with direct input (DI) into PAs/monitors, as well as into studio desks/DAWs. Along with the POD, Line 6, also now part of Yamaha, is still in the same business with their extensive Helix range.

Alternatives to the Line 6 POD and Helix units include the Axe-Fx III from Fractal Audio, which is a pro‑level amplification/effects processor suitable for both guitar and bass. Meanwhile, Kemper Amps took a slightly different route with their Profiler, which has all‑in‑one effects, amplifier and speaker cabinet profiles designed for both guitar and bass.

Just to finish off, there are numerous boutique effect pedal manufacturers that produce stomp boxes, often to very high degrees of quality, including brands such as Way Huge, TC Electronic, EarthQuaker Devices, Darkglass, Aguilar, Origin Effects, Free The Tone, Providence, Source Audio, Walrus Audio, ZVEX, Mooer Audio, Sansamp, Digitech, Eventide, Strymon, JHS, Keeley and Empress Effects.

Iconic (and other) bass guitars

The next sentence is likely to be highly provocative and intentionally so. While there are innumerable bass guitar models out there from 1951 to the current day, there are probably only four bass guitar models that can truly be called iconic (i.e. something that is widely considered to epitomize an era, culture, community or place). The four key instruments – none of which are based on guitar equivalents – that stand head and shoulders above the rest are:

Truly iconic bass guitars:
Fender Precision Bass (1951‑date)
Fender Jazz Bass (1960‑date)
Rickenbacker 4000 series (1957‑date)
Music Man Stingray Bass (1976‑date)

There are, however, many Japanese basses produced by companies such as Ibanez, Tokai, Greco, Jedson, Westone, Teisco, ESP/LTD, Fernandes and Aria.

“Without the Fender bass, there’d be no rock n’ roll or no Motown. The electric guitar had been waiting ’round since 1939 for a nice partner to come along. It became an electric rhythm section, and that changed everything.” – Quincy Jones (1933‑)

Bass in the (near) future

It is difficult for, and unfair of, me as a guitarist, to predict any sort of unified future for the bass guitar but I’ll give it a shot.

The traditional conservative brigade will still stick to tried and tested instruments and equipment. Musicians looking for something a bit different will probably want to experiment with the format, for instance number of strings, scale lengths, pickups and electronics. If anything there will be more radical and custom bass guitar designs from up‑market and boutique luthiers that diverge from the traditional archetype set by Fender over 70 years ago. Many additions to the form extend the flexibility of the core instrument, so it may be a case of further evolution, rather than revolution.

Bass amplification will continue to diverge from its simple valve origins and continue to embrace the digital realm, probably dispensing with backline amps/cabs altogether with signals being DI’d into desks/PA/monitors.

While bass players haven’t been particularly well served in the past for bass‑specific effect pedals, I anticipate that bass effects will achieve greater representation, including some out‑there effects not currently available to guitar players.

Bass guitar players have struggled to compete, with synthesisers dominating the world of modern electronica, dance and popular music. At least, for now (thankfully), the bass guitar remains essential to most guitar‑based music in a sort of symbiotic, co‑dependent relationship. As long as guitars keep going, so will bass, and vice versa. Bass players, being ever inventive individuals, will adapt and cultivate new ways to keep the instrument relevant, current and in the limelight for decades to come.

Technique‑wise, there will continue to be the traditional approaches towards walking bass lines, typically using the fundamental root/fifth styles that has been the general mainstay of modern music for decades. In contrast, there will be many more amazing virtuoso bass players who see the versatility and potential of the instrument in its own right.

So, other than tangible incremental progress around the margins, there is probably not a whole lot that will change profoundly in the near future. I may be wrong with that last sentence. In many ways, I hope so!

Interestingly, while the upright double bass continues to appear in modern music from time to time, the solid body fretted electric bass hasn’t really made any headway into the clique of conservative classical orchestral music, which still relies heavily on the traditional, some may say archaic, acoustic upright double bass.

Resources

Periodicals dedicated to bass guitar may be the best place to keep up‑to‑date with the technology and equipment associated with the instrument. Publications include Bass Musician Magazine, Bass Player Guitar Magazine, Bass Guitar Magazine, Bass Magazine, Bass Musician and Bass Gear Magazine.

Online resources include Music Radar, TalkBass.com, Basschat and No Treble. There are also many books on bass guitars and bass playing techniques, including the inevitable, ‘Bass Guitar For Dummies’.

As far as purchasing bass guitars, there are the large Internet sites, brick & mortar retailers and the usual online sites, Reverb.com and eBay. For vintage and rare bass guitars, there are outlets purely for basses including (in the UK) Andy Baxter Bass, The Bass Gallery, The Bass Centre, Vintage Bass Room and ClassicandcoolGuitars.

Some final thoughts

I certainly learnt a lot from researching and writing this article. At first sight, there may seem to be quite a bit of relevant information on the Internet. It is only when one starts to dig deeper and attempt to put something together that makes some form of sense that things rapidly become unclear. All of a sudden, much of the available information seems incomplete, contradictory, vague and/or outright erroneous. In the end, it comes down to evidence and corroboration but sorting the wheat from the chaff isn’t always easy. It seems that online information about vintage guitars is far more reliable than that about vintage basses. There are far too many poorly informed people who invent facts and present opinion as truth.

Despite my best attempts to piece things together, I may have fallen foul of the same issues raised above. However, I have tried very hard not to fill in gaps with assumptions and/or fiction. While I endeavour to be thorough and rigorous, my approach isn’t academic and I don’t have the time, funds or energy to provide the last word in scholarly fact. The contents herein should therefore probably not be relied upon too heavily. This article should, for that reason alone, be regarded as my best intention to balance fact with entertainment.

“Believe nothing, no matter where you read it, or who said it, unless it agrees with your own reason and your own common sense.” – Buddha (Siddhārtha Gautama – c.480‑400BCE)

This is just the sort of article that would benefit greatly from images to illustrate and break up the narrative. Sadly as a (broke) not‑for‑profit entity, I cannot afford the costly copyright/royalties charged for the use of relevant images, so I have had to rely on very limited free/public domain resources or my own photographs. I apologise for the thousands of words used to describe what images could do in none. Once again, no AI was used in the research and writing of this tome – only my own hard work.

NB. Apologies to anyone disappointed by the wait for a cheap, clichéd joke at the expense of ‘the bass player’! T’ain’t gonna happen here. Love ‘the bass player’.

CRAVE Guitars’ ‘Album of the Month’

Given that this month’s article focuses on the fascinating history of the bass guitar, it seems only fitting to select an album that demonstrates the virtuoso bass playing of one of the greatest bass guitarists of all time, Jaco Pastorius (1951‑1987) and his famous modified fretless Fender Jazz Bass.

Weather Report – Heavy Weather (1977) – The seventh and most commercially successful studio album by the American jazz fusion band. ‘Heavy Weather’ was the first album with Pastorius on full‑time bass duties. The smooth jazz funk production of the album, which was released at the peak of the punk rock movement in the US and UK, stood in stark contrast to the otherwise brutal sounds of the late 1970s. Given that it sold in huge numbers (and still does) is testament to the composition and musicianship on display. Initial sales were about 500,000 and total sales to‑date are over 1.06 million. Other Weather Report albums may be ‘better’ according to purists but this is the one I heard first and it has stuck with me over the years.

To me, this album hit me right between the eyes about what virtuoso bass playing can be like. There are many, many other artists and albums that could arguably take the acclaim, for instance Stanley Clarke’s successful solo album, ‘School Days’ (1976), but on this occasion, the late, great Jaco (& co.) takes the accolade, such as it is.

“I’m the greatest bass player in the world” – Jaco Pastorius (1951‑1987)

Tailpiece

Well, there you go. I think that most of us love a bit of decent low bass in our music. I hope y’all got something out of this fleeting exploration into the defining instruments, artists and music of the lower registers. I think the narrative works well as a complement to the launch of CRAVE Basses at the end of 2023, but that’s just my (obviously biased) opinion.

I hope you feel inclined to come back next month to see what’s currently fermenting in the CRAVE guitars’ secret brewery.

Truth, peace, love, and guitar music be with you always. Until next time…

June 2018 – A Potted History of the Guitar Part IV

by Tony Drew | posted in: History, Introduction, Observations | 0

Without further ado, let’s get stuck into Part IV of the history of the guitar. As the story was left at the end of the last article during the 1920s and early 1930s, something new was needed to ensure that guitars would not only be able to compete with other instruments in a live situation but also become the catalyst for a musical revolution to mirror what was taking place in wider society. Just in case you were lulled into a sense of coherent continuity, this month’s article is a bit different from what has been covered so far.

This part is presented as part of a whole. If you wish to recap on previous articles in the ‘Potted History of the Guitar’ series, you can access them here (each part opens in a new browser tab):

Please remember that this is written purely for entertainment purposes and is not intended as an academic tome. While I have tried to be diligent in my research, there are undoubtedly improvements that could be made, so corrections and clarifications are genuinely welcomed. This is quite a long article, so I hope you are sitting comfortably.

Needing to be heard

The problem for guitarists in the 1920s was a simple but fundamental and frustrating one. The amount of volume that could be attained from purely acoustic guitar designs had got as far as it was likely to get at the start of the 1930s. Guitarists were still struggling to be heard in noisy live music environments as part of jazz, swing, big band and dance orchestras. Despite the strengths of steel strung folk guitars, archtop guitars and resonator guitars, the lack of volume continued to be a problem for guitarists throughout the early part of the 20^th Century. A number of clever innovations attempted to help acoustic guitarists cut through the mix but they didn’t really capture mainstream attention and passed into obscurity, leaving demanding musicians still yearning for louder instruments.

Creative inventors, engineers and entrepreneurs were determined to find a workable solution. Perhaps the biggest game‑changing watershed in the entire history of guitar building was about to take place in America in the 1930s. The transformation depended on coincidental and mutually dependent developments; the magnetic pickup, the portable valve amplifier and its associated loudspeaker(s). Undoubtedly, the amplifier came first, simply because it could be driven by other inputs, such as early microphones, while the pickup followed to take advantage of the opportunity. Logic suggests that the converse would make little sense, as a pickup without some means of manipulating the signal s essentially redundant.

By the end of the 19^th Century, early microphones were being used in telephone, broadcasting and recording industries. In 1916, the first condenser microphone was invented and in 1923, the first moving coil and ribbon microphones were developed. Given the timing, it seemed logical to experiment with microphones to capture the sound from acoustic guitars. However, the results weren’t particularly successful and the microphone proved to be a dead end for guitarists at the time. A more practical and reliable alternative was required to capture the physical energy produced by a stringed instrument and convert it into a usable electrical signal that could then be amplified and output.

Before starting to look at the early electric instruments that changed modern guitar music forever, it is worth taking a temporary detour to look at the catalysts that led to the step change. Once the technical inhibitors had been overcome and the various elements combined, electric guitars became a realistic and achievable proposition.

The electro magnetic guitar pickup

By the 1920s and 1930s, the science of using magnetism and wire coils to induce an electric current had been understood for several decades. It would, however, take some ingenuity to apply the various scientific principles involved to overcome the specific practical problems experienced by guitarists of the time. Within this context, we need to go right back to basics as a starting point.

An electromagnetic guitar pickup is basically a passive transducer that uses Faraday’s law of induction, named after English scientist Michael Faraday (1791‑1867), to produce an electromagnetic force. The physical movement of the vibrating steel string of a strummed or plucked guitar disturbs the magnetic field and induces a small voltage of between 100mV and 1V through the coil. This differs from a simple microphone, which works by converting pressure variations in the air (sound waves), into the mechanical motion of a diaphragm, which in turn produces an electrical signal (depending on the type of technology used).

A simple electromagnetic guitar pickup is generally constructed from one or more permanent magnets, wrapped many thousands of times in a coil made of fine copper wire. Most early guitar pickups comprised only one magnet and coil, hereafter referred to as single coil pickups. The weak electrical signal is then passed down an electrical lead to a separate amplifier where the signal is multiplied many times to drive a passive loudspeaker that reproduces the original signal at greater volume.

Unlike a microphone, the electromagnetic pickup does not reproduce the actual acoustic sound waves emanating from the guitar. The natural resonance of the instrument may cause the strings to vibrate in a certain way and this variation is picked up by the transducer, which may explain the differences in sound between two instruments using the same pickup, electrics, amplifier and speakers. As a result, at least in the early days, the characteristics of the pickup combined with the rest of the signal chain probably had more to do with the sound that audiences heard, rather than that of the actual instrument itself. There are innumerable permutations in which the basic components of magnets and wire can be configured to produce different outputs and over the years, pickup designers have used these variations to differentiate their pickups from those produced by others.

Gibson employee, Lloyd Loar had experimented with stringed instrument pickups as early as 1924, shortly before he left the company. Loar attempted to produce an electrical signal from vibrations passed from the strings through the bridge to the magnet and coil. Loar’s work did not lead to a successful product and guitarists had to wait a while longer.

American inventor and musician, George Beauchamp, who had been involved with the National String Instrument Corporation and the development of their resonator guitars, was also involved with another resourceful enterprise at the beginning of the 1930s. He teamed up with Adolph Rickenbacher to form the company was originally called Ro Pat In Corporation, which later became Electro String Instrument Corporation and later still, Rickenbacker, a name that most guitarists will recognise. Ro-Pat-In was instrumental in taking a fundamental new approach to electric guitar design.

Through Electro String, Beauchamp filed a patent in June 1934 setting out his pickup design as part of a complete ‘Electrical Stringed Musical Instrument’. Beauchamp’s ‘horsehoe’ pickup design comprised two ‘U’‑shaped magnets encircling the strings. Beauchamp’s application was granted by the U.S. Patent Office in August 1937. The patent was important because it was for a solid body electric guitar using a magnetic pickup, not just the pickup on its own – the development of the instrument will be covered in the next part of the story so, for now, the focus is solely on the pickup.

Ironically, in February 1936, Guy Hart filed a patent on behalf of Gibson for an ‘Electric Musical Instrument’ and this was awarded by the Patent office in July 1937, just 28 days before Beauchamp’s earlier patent application was confirmed.

Although unknown at the time, another single coil guitar pickup patent was filed in September 1944 by American inventor and entrepreneur Leo Fender. That application was for a ‘pickup unit for instruments’, which was awarded in December 1948. Although not as historically significant as other pickup patents, it was a clear indication of the direction that Leo Fender was heading prior to founding the company that would bear his name.

Another important principle of basic physics caused a significant problem for early pickup designers, and it still does even today. In addition to the desirable characteristic of electrical induction for guitar pickups, electromagnetic coils also act as directional antennae. As far as musical instruments go, this unwanted ‘feature’ means that single coil pickups not only pick up string vibrations but they also pick up interference from alternating mains current used by electrical appliances. Depending on position of the pickup in relation to other electrical equipment, of which there are usually many in a live music venue, the interference manifests itself as a continuous and insistent hum, which is then in turn amplified by a guitar amplifier.

One ingenious solution to the problem of mains‑induced hum was to invent a guitar pickup that still produced a signal from string vibrations while eradicating the interference from nearby electrical equipment. The clever answer was the invention of the ‘humbucking’ pickup, which uses two magnets, each with a coil of wire wound in opposite directions. Electrically induced mains interference affects both coils equally and, because each one is wound in opposing directions, the interference is cancelled out, thereby eradicating (or ‘bucking’) the hum. More importantly, not only do the coils still induce a voltage, they output a stronger signal because there are two coils instead of one. As the problem is all but removed at source, there is no hum to be amplified.

Arguments persist as to who invented the humbucking guitar pickup. Many commentators give the accolade to Seth Lover (1910‑1997), who was an electronics designer working for Gibson at the time and filed a patent in June 1955. Lover’s closest competitor in the race to be recognised for the humbucking pickup came from Joseph Butts, who later worked for Gretsch. Butts filed another humbucking pickup patent some 18 months later in January 1957. It was Butts’ application that was awarded first in June 1959, while Lover’s patent was awarded in July 1959. As far as many working musicians were concerned, the invention was successful and that was all that mattered.

Generally speaking (but not always, especially if obscured by a cover), it is relatively easy to spot the difference between slim single coil pickups and their larger dual‑coil humbucking counterparts. The latter normally have two coil bobbins traditionally mounted side‑by‑side. Within these two broad types, there are many, many different makes and styles of pickup to suit most needs.

Hum is not the only affliction that electric guitar builders have to deal with. All electromagnetic pickups, even those produced today, are prone to audio feedback, which is often heard as an undesirable high pitched shriek or howl. Feedback is a phenomenon called the Larsen Effect after the Danish scientist Søren Absalon Larsen (1871-1957) who discovered it. Audio feedback is caused by a sound loop that exists between an audio input such as a pickup or microphone and an audio output such as an loudspeaker fed by an amplifier. The electrical signal from the input is amplified through a loudspeaker and is then picked up again by the input and so on, continuously. The sound of the feedback is shaped by the resonant frequencies and proximity of the various components in the loop, including room acoustics. Most of the time, feedback is considered problematic and often unpredictable. However many guitarists have learned to harness and control feedback in a positive musical way to create additional sounds.

Some contemporary pickup manufacturers go to great lengths to replicate the authentic tonal characteristics of vintage pickups. One of those widely imitated pickups is also probably the most famous of humbucking pickups. Used on Gibson guitars from the late 1950s, the PAF (Patent Applied For), named after the black sticker on the baseplate, has come to define Gibson’s sound for many guitarists. The PAFs are particularly revered, as they were used in sunburst Gibson Les Paul Standards from 1958‑1960, often regarded as the ‘golden years’ for Gibson.

Today, many independent pickup builders not only pay homage to vintage designs but also strive to create their own distinctive reputation. Third party pickup builders may make OEM (Original Equipment Manufacturer) and aftermarket pickups in a huge range of types. Such companies include Seymour Duncan, Di Marzio, EMG, Lollar and Bare Knuckle, among many others. Pickup choice in the 21^st Century is very much down to personal preference and the options are nigh on infinite – very different from the 1930s.

The sounds generated by single coil and humbucking pickups are noticeably different. Not only do single coil pickups tend to produce a weaker signal, they sound thinner and cleaner, while more powerful humbucking pickups tend to sound fatter and warmer. Guitarists noticed this variation and took advantage of the differences to shape their own playing style and develop their distinctive tone. In addition, humbuckers are often considered better suited to overdriving pre‑amplifiers, thereby adding some controllable, distinctive and desirable harmonic distortion, making them popular in higher gain rock music.

By the 1950s manufacturers were commonly using two or more pickups on a guitar for added tonal versatility, initially adding a second or third pickup of the same type, for instance commonly used configurations include 2 humbuckers (e.g. Gibson Les Paul) or 3 single coils (e.g. Fender Stratocaster). Many guitar makers today mix different types of pickups on one guitar to broaden the range of sounds available.

Some pickup arrangements also allow pickups to be engaged in series or parallel or in/out of phase to give musicians a greater number of tonal options. Since the 1970s, pickup designers have enabled the signal from the two coils of a humbucking pickup to be ‘split’ (NB. not ‘tapped’). By using a switch, guitarists may enable a split humbucker to sound either like a traditional humbucker or to emulate the distinctive sound of a single coil pickup. All these various techniques provide guitarists with greater flexibility from their pickup(s).

Simplistically, guitar pickups may also be described either as passive or active. Passive pickups are the basic devices that have been described so far, while active pickups incorporate some form of electronic circuitry in the guitar to modify the signal, normally powered by an on‑board battery. Outwardly, there is often little to distinguish whether pickups are active or not. Putting active electronics into a guitar has been around since at least the 1960s and can range from a simple pre‑amp to boost the pickup signal to elaborate on‑board effects or even low powered amplification.

Since its inception 1930s, the humble guitar pickup has been adapted into many diverse forms. The majority of pickups in the early 21^st Century remain passive single coil or humbucking types. However, there have been other pickup innovations along the way diverging from the norm. These alternative technologies include, amongst many other pickup types; hexaphonic (that feed individual string signals to MIDI/synthesizer controllers), piezoelectric (using crystals to induce current), microphonic (converting sound wave vibrations to electricity), electrostatic (using a capacitor to vary electrical capacitance), optical (interrupting a beam of light detected by a sensor), etc.

The understanding of the science behind pickup materials and dynamics between the components has been improved and refined significantly since the 1930s. However, the basic principles behind the passive transducing electromagnetic pickup remain pertinent today and are likely to remain so for the foreseeable future. Magnetic pickups are, by far, the most common type used by electric guitars in the late 20^th and early 21^st Centuries. This may be about to change.

With the digital revolution, there are numerous innovations occurring today that will lead to radical new pickup designs in the future. Future musicians can expect many new ways of converting the vibrations from humble plucked guitar strings into electrical signals that can be manipulated in ways we cannot yet contemplate. The possibly unstoppable migration from analogue to digital technology will continue. We can only speculate as to how far digital processes will encroach into the hitherto staunchly analogue domain of the guitar. Already, we have seen digital devices that enable the output from a guitar’ pickup to ‘model’ other types of guitar and even other instruments by modifying the signal digitally. We have also seen guitars as being a source trigger for external synthesis and various guitar synths have been around since the 1970s. It seems somewhat ironic that the digital age is enabling ever more accurate simulations of the earliest analogue pickups including the original’s crude and accidental inconsistencies.

While this section of the story is about guitar pickups, it is worth remembering that pickups have also been used successfully on many other types of stringed instrument.

Once the concept had been proven, the next step was to apply actual real‑world pickups in a practical way. There were essentially two methods of implementing an electromagnetic pickup for use on a guitar. One way was to add a pickup to existing acoustic instruments and the other was to invent an entirely new type of guitar with the pickup as an integral part of the design. How these two approaches came about will be covered in the next part of the story.

The pickup on its own, however, is of little use in isolation. Another crucial part of the equation was to take the weak signal from the guitar’s pickup and manipulate it electronically to make it much louder, which is where a completely different solution was needed.

The electric guitar amplifier

Possibly the major challenge with introducing guitar pickups was to turn the tiny voltage produced by the pickups into a sound that provided practical real‑world volume and tone for working musicians playing in noisy bands on the road.

The essential piece of equipment actually comprises two crucial components, the electrical amplifier and one or more loudspeakers. Amplifiers largely fall into two broad categories – either as discrete units comprising the electronics in a ‘head’ unit with loudspeakers installed in a separate cabinet, or with both amplifier and speaker(s) integrated into a single ‘combo’ amp. It is worth looking at the origins of both the electronics and the loudspeaker separately.

For travelling musicians from the 1930s on, amps also needed to be portable, so size and weight were particular considerations, as was electrical safety, durability and reliability. In addition, some degree of industry standardisation to enable interchangeability between instruments, electronics and venues was important.

The Amplifier

In the early days, amplifying a signal from a pickup was all that a guitar amp was really required to do. Controls were very basic, usually just a single input channel with a volume and, maybe, a tone knob. It would take some time before more flexible electronics were added to these basic amplifier circuits. Nowadays, the diversity of amps ranges from the very simple to the incredibly complex. The latter often including, just for starters, multiple switched channels, gain controls, effects loops, digital modelling alongside advanced EQ, flexible on‑board effects and digital interfaces. However, the fundamental principles of amp utility haven’t really changed that much since amps were first invented in the 1920s and when guitarists started to use them in the 1930s.

Put very simply, an amplifier is made up of active electronics that are designed to take an input signal, multiply it many times in strength and output it to a loudspeaker at a volume that is considerably louder than the original input. The electronics of an amplifier comprise essentially two discrete parts, a pre‑amp that controls the incoming signal and shapes it ready to be boosted and output by the power amp section that then drives the loudspeaker(s). It is these two amp sections that determine the overall character and volume of the audio output.

Amplifier output is usually measured in watts and provides a crude indication of power output (volts x amps = watts). The relationship between watts and sound pressure levels heard by the human ear is logarithmic. Generalising, it takes ten times the output power in watts to double the perceived audio volume. In addition, it takes considerably more amplifier power to reproduce low-frequency sound, especially at high volume, so bass amps tend to have higher power output ratings.

While early amplifiers were configured to the environment in which they were most likely to be put, such as practice, studio or stage amps, many modern amps use various techniques to minimise this artificial distinction, such as master volume controls, power attenuators or circuits used to modify amplifier stages to suit.

Up until the 1970s, thermionic valves – also known as vacuum tubes – were a principal electronic component and one that contributed significantly to both the power and sonic character of the amplifier. A valve is a relatively simple device used to control electrical current between its electrodes. The first valve was invented in 1904 by English electric engineer John Ambrose Fleming (1849-1945).

At its most basic, a valve comprises an external glass container used to maintain a vacuum is attached to the valve base. Inside the valve there is a heater, an electron‑emitting cathode/filament and an electron‑collecting anode/plate. Electrical current, in the form of negatively charged electrons, flows through the vacuum in one direction only from the cathode to the anode. An electrical grid can be used to control the current and is the one often used for amplification because the grid can be used to vary the number of electrons reaching the anode and, thereby, controls the amount of gain. Valves are often described by the number of electrodes, for instance; diode, triode, tetrode or pentode valves (2, 3, 4 and 5 respectively). The humble valve has been used in many applications, such as amplification, rectification, switching, oscillation, and display.

Valves come in many shapes and sizes and vary according to the function they are required to perform in the amp stages. Generally speaking, pre-amp tubes tend to be smaller, while power amp valves tend to be larger.

There are numerous alternatives and variations of valves and there isn’t room to cover the range of technical differences. Thankfully, there has been a degree of commonality in amplifier design over the decades. Typical valves used in pre‑amps include models such as the 12AX7/ECC83. Typical valves used in power amps include models such as the EL-34, EL-84, KT66/77/88, 6L6/5881 and 5150. Valves impart a characteristic ‘natural’ sonic signature and tend to be sensitive to a guitarist’s playing dynamics, which is why they are still widely favoured by many musicians to this day. While technically outdated and obsolete, there is a notable modern‑day industry built around valve production, amp manufacturing and valve amp maintenance.

The valve is the technological precursor to modern semiconductors. Semiconductors are often made of silicon, although they can be made from other materials, such as germanium. A transistor is a solid‑state semiconductor that roughly performs the same function as a valve and is commonly used for amplification. Transistors are smaller, cheaper, lighter, run cooler, are more reliable and more resilient than valves. Some manufacturers produce hybrid amps that aim to take the best characteristics of both valve and transistor technologies.

Taking things even further away from archaic valve technology, electronics using complex digital microprocessors are commonplace. Not only can DSP (Digital Signal Processor) chips produce their own sounds but also they enable a single unit to model a multiplicity of amplifier models that would be impossible using traditional technology. In addition, they can also emulate multiple effects, speaker cabinets, microphone placements, studio interfaces, and so on. Reliable and robust digital processing amps able to be used equally well at home, in the studio and on stage are once again attempting to usurp territory previously held by archaic analogue amps.

Specialist amps are made to make the most of other, albeit similar, electric instruments. For instance, electro‑acoustic guitars (acoustic guitars with pickups) produce a wider frequency range and tend to be ‘cleaner’ sounding than electric guitar amps, which has led to increasingly elaborate amp electronics to cater for the particular needs of acoustic guitar players. Bass amps and speakers are also engineered specifically to provide for the demanding amplification used by bass guitarists. There are no hard and fast rules, the lines are not always clearly drawn and there is inevitably some interchangeability between the general types.

One of the keys to success is to match the characteristics of the amplifier stages to the loudspeakers, so it is worth looking next at the humble loudspeaker and the important part it plays in the guitar sound’s signal chain.

The Loudspeaker

The latter part of the 19^th Century was ripe for invention in the field of sound reproduction. As with other sections, only a few of the key milestones can be covered here. Prior to the invention of the modern loudspeaker, megaphones and bulky ‘radio horns’ had been used to increase acoustic volume. However these proved impractical because of their size and weight, limited frequency range and low sound pressure levels.

German teacher, Johann Philipp Reis was, perhaps, the first to develop a rudimentary type of experimental electric loudspeaker in 1861. Alexander Graham Bell was the first to patent his loudspeaker design in 1876 for use in his telephone, shortly followed by Ernst W. Siemens who patented his ‘magneto-electric apparatus’ in 1874. Thomas Edison and Nikola Tesla were also experimenting with sound around the same time. By 1898, Horace Short was working with compressed air drivers and Oliver Lodge was developing a ‘dynamic’ speaker using magnets and moving coils with horns to amplify sound. Danish‑American engineer Peter L. Jensen (1886-1961) is often cited as co‑inventor of moving coil speakers in 1915 and he started applying the technology for use in real world situations. Jensen founded his company, Magnavox, in 1915 to market products for telephones and public address (PA) systems. Magnavox is now part of the massive Philips corporation.

Things changed considerably in the 1920s with the introduction of the first amplified moving coil loudspeaker using a conical paper speaker diaphragm, which was invented in 1925 by Edward W. Kellogg and Chester W. Rice, both of whom worked for General Electric in New York, USA. Their research was important as it established both the principle of the amplifier to boost a signal and a speaker able to reproduce a wide and uniform frequency range. Rice filed a patent for the electrodynamic direct radiating ‘loud speaker’ in 1925, which was awarded in April 1929. Their speaker was introduced to the market under RCA’s Radiola brand in 1926.

Early speakers used powered electromagnets, as permanent magnets were scarce at the time, although Jensen released a fixed magnet speaker in 1930. Lightweight Alnico alloy magnets became available after WWII, making the technology more accessible enabling further innovations to take place. Other inventions along the way included, for example, 2‑way systems using a crossover to separate frequency bands (1937) and coaxial speakers (1943). Once the concept of the moving coil speaker had been proven in practical applications, it has become the de facto standard within the music industry for nearly a century.

The loudspeaker, as we know it today, is essentially a mechanical electroacoustic transducer that serves the opposite function to a microphone in that it converts an electrical signal into sound waves. A traditional moving coil speaker is passive in that it relies on an already amplified signal being fed to it and it doesn’t require its own power supply. The incoming amplified signal is fed into a coil of wire, known as the voice coil, suspended between the poles of a permanent magnet. The voice coil is attached to the apex of a conical diaphragm known as a speaker cone, originally made of paper. The outer edge of the cone is mounted within a fixed metal chassis, usually within a cabinet. The electrical signal makes the voice coil move back and forth rapidly within the magnet thereby pushing on the cone to produce sound waves. The more air that the moving speaker cone displaces, the louder the perceived sound is. Different sizes and types of speaker are used to deliver different sound frequency ranges. Generally, larger speakers are used to deliver lower bass frequencies and smaller ones used for higher treble frequencies.

Loudspeakers are usually attached to a flat panel (baffle) with circular holes cut into it such that the sound waves produced by the speaker cones can escape directly into the listening environment. The baffle with its speaker(s) is normally mounted inside either an open‑back or closed‑back wooden cabinet.

Like amplifier outputs, speaker output is usually measured in watts, which is the electrical power needed to drive the speaker. More watts generally, although not always, indicates greater volume. Like all electrical devices, a speaker provides some opposition to the signal being fed into it, called impedance, measured in ohms. Some speakers are ‘hard to drive’ and have a low impedance, which means that it requires greater current from the amplifier to result in the same output level than a high impedance speaker. As a result, it is important to match a speaker’s characteristics to the amp that is driving it.

Most loudspeakers, even those produced today, are relatively inefficient devices with only about 1% of the electrical energy being converted into acoustic energy. Most of the remaining energy is converted into heat. The sensitivity of the speaker describes how much relative electrical energy is converted into sound pressure level, measured in decibels.

The other important factor for loudspeaker performance is its frequency response. Human hearing generally covers the range 20-20,000 Hertz (cycles per second). People’s sensitivity to frequencies is not uniform and it varies depending on pitch. Human hearing is usually most sensitive in the 2,000-4,000 Hertz range.

Famous names in the field of loudspeaker manufacturing today include Celestion, Jensen, Weber, Electro Voice, JBL, Bose, Fane, Altec Lansing, Mackie, and Peavey amongst many others.

Despite its many drawbacks, the moving coil loudspeaker was (and generally still is) the most effective mechanism for the job and they remain in very wide use today. Speakers come in a multiplicity of shapes and sizes and are used in so many different ways. However, like the pickup and amplifier, the basic principles of speaker design can be traced back to the early part of the 20^th Century.

Guitar Amps

Initially, bulky battery‑powered valve amps and speakers were used in PA systems and in movie theatres of the time. Because of their bulk and relative fragility, these early systems tended to be fixed installations. From c.1927, portable AC mains‑powered amps became available and musicians started to adopt the technology.

In 1928, Stromberg‑Voisinet advertised the first electric instrument and amplifier package. However, it was not a commercial success and no verified examples exist today. In 1929, Vega introduced a portable amplifier to be used with banjos.

It wasn’t until 1932 when the Electro String Instrument Corporation – later to become Rickenbacker – was formed to bring the electric guitar to market that things really took off. Electro launched a ‘high output’ guitar amp to accompany their new solid body electric lap steel guitars, as Hawaiian music was highly popular at the time across America. The first commercial solid bodied electric guitar and amplifier made by Electro String essentially established the format for early combo amps comprising an electronic amplifier mounted inside a wooden cabinet along with a speaker. The new combo amp also had a carrying handle to make it portable and, shortly after, the company added metal corners to protect the cabinets in transit.

In 1933, Dobro introduced the first guitar amp combo with twin 8 inch speakers. By around 1935, the demand for amplified electric guitars became unstoppable and the electric guitar music revolution had begun. Other companies such as National, RCA Victor, Audio-Vox, Vivi‑Tone, Premier, Vega, Kay, Valco and Volu‑Tone, promoted their own amps to musicians, with varying degrees of success during the 1930s and 1940s. Gibson was also experimenting with amplifiers in the early 1930s although none were made commercially available at the time. Most of the early valve amplifiers were low powered by today’s standards, usually less than 10-15 watts and using small speakers, often of 10 inches or less in diameter.

In 1938, American electronics technician, Clarence Leonidas ‘Leo’ Fender (1909-1991) established Fender Radio Service to repair a wide variety of electronic equipment. He found that musicians would come to him for PA and amplifier repairs and rentals. Seeing the potential of the music industry and started to focus more on musical equipment manufacture. Fender began a short‑lived venture in 1944 with Clayton ‘Doc’ Kauffman, a former employee of Rickenbacker called K&F Manufacturing Corporation with the intention to build Hawaiian lap steel guitars and amplifiers.

In 1946, after Kauffman and Fender parted company, Leo founded the company with which he will forever be associated, Fender Electric Instrument Manufacturing Company, based in Fullerton, California. Shortly thereafter, they introduced the first guitar amps carrying the Fender name. Early Fender combo amplifiers included the Fender Princeton (1947-1979) and Champion 800 (1948-1982).

In 1952, shortly after Fender introduced their Broadcaster guitar which would become the legendary Telecaster, the company introduced what would be, perhaps, its most celebrated combo amp, the famous Fender Twin. The Twin moniker derived from its dual 12 inch speakers. The Twin has been released in many versions over its long history, with its power output ranging from its original 25 watts to a high of 135 watts in the late 1970s. The perennial Fender Twin remains in production today and has become an industry standard.

Meanwhile, based in Kent, England Tom Jennings (1918-1978) founded British company Vox in 1947 to produce musical equipment. It wasn’t until 1958 that Vox released its first guitar amp, the 15‑watt AC15. A year later, at the request of The Shadows’ guitarist Hank Marvin, Vox introduced its most famous model, the AC30, intended to compete with America’s powerful Fender Twin amp. The AC30 proved to be a very successful product and in updated form, it remains in production today.

It wasn’t until the 1950s that mass produced guitar amplifiers really became commonplace and incorporated many of the features now expected from an amp including, for instance, multiple tone controls, tremolo and reverb.

In addition, contemporary popular music of the time was developing rapidly and guitarists began to experiment by overdriving their amplifiers to distort the guitar’s sound at much higher volumes. From the mid‑1960s guitarists sought to control the level of overdrive and distortion (also known as clipping) as a creative tool. One particular characteristic of natural valve distortion is that clipping also tends to compress the signal as the volume is increased, meaning the output tends to sound ‘thicker’, rather than louder, emphasising the guitar’s sustain.

Guitarist Dave Davies of English band The Kinks is often credited with popularising guitar distortion. On one occasion, Davies himself admitted to slashing the speaker cone of his Elpico AC55 ‘little green amp’ with a razor blade out of frustration and in the process of doing so, he made it sound distorted and nasty. The Kinks’ song, ‘You Really Got Me’ (1964) is often cited, rightly or wrongly, as the first hit record featuring heavy guitar distortion (using a Vox AC30).

The search for new guitar sounds in the 1960s helped to ignite the drive for compact guitar effect pedals, initially with simple fuzz and wah effects. A whole industry developed during the late 1960s and 1970s including brands such as Electro‑Harmonix, MXR, Maestro, Boss and Ibanez, amongst many, many others. Effects have ever since been used to complement guitars and amps as an integral part of a musician’s signal chain. The market for effect pedals has grown into a massive industry in its own right.

The development of guitars, amps and popular musical styles of the 1950s defined the template on which succeeding generations of guitarists would build incrementally. Many modern amps and amplifier innovations hark back to the best examples of this ‘golden’ period. Driven by the success of the 1950s, particularly the popularity of Fender amps, the quest for more volume seemed unquenchable. The first 100 watt amps were made by Leo Fender for surf guitarist Dick Dale, while Jim Marshall of legendary British amplifier manufacturers Marshall did the same for Pete Townshend and John Entwistle of rock band The Who. Dr. Jim Marshall OBE was affectionately nicknamed, ‘the father of loud’.

High power, high gain valve guitar amps became the norm at the end of the 1960s and into the 1970s. It was not uncommon to see large stages filled with gargantuan ‘stacks’ of loudspeaker cabinets powered by banks of high powered amps. Marshall is the brand most associated with the classic guitar stack, which at its simplest comprises a 50 or 100 watt amp on top of two 4×12” closed back speaker cabinets, thanks again to Pete Townshend of The Who as well as the likes of Jimi Hendrix and Eric Clapton. The guitar stack has since become inextricably linked with hard, heavy and metal rock music. Music and its essential components very much reflected the cultural and social changes of the times.

There have been several technological challenges to the humble valve. A concerted trend away from vacuum tubes towards solid state transistor amps occurred in the 1970s, led by companies like Roland, Peavey and H/H. Other manufacturers adopted a best‑of‑both‑worlds approach by making hybrid solid state/valve amps, led by Leo Fender during his time with Music Man.

Arguably, Fender, Marshall remain the two predominant and recognisable amplifier brands and, respectively, have come to define the ‘American sound’ and ‘British sound’ respectively. Notably, unlike Fender, Gibson has never had much commercial success with building guitar amps, despite producing some credible models along the way. There are now a myriad of other amplifier manufacturers including famous brand names such as Mesa Boogie, Peavey, Ampeg, Randall, Rivera, Bogner, PRS and Supro in America, and Vox, Orange, Blackstar, Victory, Hi-Watt and Laney in the UK. Outside the USA and UK, there are many successful brands including Hughes & Kettner, Engl, Line6, Roland, Yamaha, BOSS, etc. In order to keep production costs down, many budget models are now produced in the Far East, while the majority of small boutique amp builders cater for the high‑end, being manufactured in limited numbers in America and Europe.

Many other famous brand names have passed into history, such as Traynor, Sunn, Multivox Premier, Univox, WEM/Watkins, Sound City, H/H, Selmer, Cornford and Carlsbro although, to be fair, some of these continue to operate in some form or other and may well be rejuvenated at some point. There are far too many brands, past and present, to mention here.

Ironically, there is increasing interest in capturing the retro sound and looks of the earliest guitar amplifiers. Many companies are now recreating classic analogue models of the past, often incorporating modern adaptations for reliability, safety and convenience to meet the demands of today’s guitarists. There are many boutique amp builders looking to take the best of old and new and present something different from the current mainstream manufacturers.

At this point, no article focusing on guitar amps would be complete without mentioning Dumble amplifiers. Dumble amps are made in very small numbers by Alexander ‘Howard’ Dumble in L.A., California, often by request of well‑heeled professional musicians. The Dumble Overdrive Special is widely regarded as the zenith of limited production boutique amps and, as a result of their quality and rarity, new or used examples have gained almost mythical status and demand extremely high values on the open market.

Despite the remarkable sustained popularity of valves, digital modelling technology is now making major inroads into the tube’s traditional territory. As the technological advances behind digital modelling processors that began with the iconic Line 6 Pod through to ever‑improving digital advances from companies like Fractal and Kemper. The audible difference between the ‘antiquated’ originals and modern digital recreations is rapidly diminishing to the point where professional musicians see a competitive advantage in moving to a digital platform.

Despite stiff competition from solid state and digital circuits, the valve guitar amp currently remains the de facto standard for many discerning professional guitarists, despite the decidedly old-world technology involved. It will be interesting to see how long genuine valve amplifiers will continue to prosper in the face of the digital revolution. Only time and hindsight will tell. It is likely that valve, analogue solid state and digital technologies will be able to coexist for many years yet.

Get connected

Guitars need to be connected to an amp in order to work, often with effect pedals in between. Before wireless and/or digital technology takes over completely, the venerable guitar lead has been the necessary link between input and output since the 1930s. At each end of a traditional interconnecting lead is a remarkable piece of analogue kit that most guitarists rarely think about but cannot live without. Similarly, guitars, amps and effects also have the other part of the same connection.

The essential connector in question is the ¼“ (6.35 mm) jack plug and its associated socket, which originally dates from c.1878. The first jack connector was invented by George W. Coy and was used for the first commercial manual switchboard at the telephone exchange in New Haven, Connecticut, USA. It is astonishing that, after nearly 1½ centuries, this enduring piece of industry standard equipment is still in ubiquitous use today, long after it became obsolete in telephone systems.

End of Part IV

This has been a self‑contained article that departs from the usual topic of guitars per se. While it might seem a lengthy, in‑depth examination, it only just scratches the surface. As I don’t have the space, knowledge or resources to write comprehensively on the subject, I highly recommend that readers wanting to delve into the historical detail take a look at the innumerable resources available on the ever‑present hinterwebby thing. NB. Credit to all original photographers for images used from Google Images.

Arguably, without the complementary inventions of the electromagnetic pickup, the dedicated valve amplifier and the moving coil loudspeaker, the revolution in guitar technology that started in the 1930s and which really took off in the 1950s would not have been possible. It is notable that the scientific principles underpinning today’s electric guitars are still relevant nearly a century later. It is, at least to me, remarkable that, technically, we haven’t really evolved a great deal over the intervening decades. Advances have been incremental refinements, rather than ground breaking. Digital technology may change all that. Watch this space.

At long last, in Part V, the story will finally unleash the breakthroughs that led directly to the early electric archtop and solid body guitars. The next revolution in guitar music making was about to happen. Who could possibly have anticipated the impact that the congruence of the three seemingly innocuous bits of music technology covered above would have when brought together.

I hope you have enjoyed the journey thus far and thank you for reading. I also hope that you’ll come back and join me on the next part of the guitar’s long journey to the current day. Time to get some vintage gear out and plug in. Until next time…

January 2016 – The Guitarist’s Friends: Amplifiers and Effects

by Tony Drew | posted in: Opinion | 0

Most of my previous articles have focused on the venerable (electric) guitar – the source of the electrical signal that becomes music. This month, while there is probably a bit of ‘preaching to the converted’, it is perhaps worth reflecting for a moment and going back to basics.

As may be blindingly obvious, the instrument itself is only one part of the equation when making amplified music. On its own, unplugged, an electric guitar would be no good in front of a big audience. As we all know, electric guitars are dependent on some sort of amplification to convert the low-level signal from the guitar’s pickups to the speakers. Losing your amp mid-gig can be embarrassing and not great for your reputation. Even an acoustic guitar needs to be amplified in order to engage a modest sized audience and there is a whole industry now built around dedicated acoustic guitar amplifiers. This isn’t really my thang, so I won’t pontificate on what I don’t understand.

The oft-forgotten component in this signal chain after the instrument is the venerable lead. I express no opinion on this essential piece of kit other than to say that good quality interconnects are vital. If you use RF transceivers, the same principle applies. These items are integral to your overall sound and it is generally worth every penny to preserve your and your guitar’s inherent musical characteristics. They may not be shiny or ‘sexy’ but scrimp on them at your peril.

Then we get onto one’s amplifier of choice. These can be anything from a diminutive, battery powered box to an impressive backline of Marshall stacks turned up to 11. It’s amazing to think that the venerable Marshall stack was 50 years old in 2015. The advent of home recording has led to an explosion in digital modelling and even the use of the iPhone/iPad can bestow tone-enhancing functions beyond the dreams of many recording pioneers. The Line 6 Pod brought about a revolution in digital amp modelling, embraced by many musicians who could see the potential opportunities of technology. Interestingly, rather than create something unique and innovative all of its own, the digital world has gone to enormous lengths to simulate the soundscape of our favourite vintage valve amps and cabinets, perhaps suggesting that those pioneers got something right in the first place.

So… what’s your favourite sounding amp? And, before you start, yes they do have a sound of their own, irrespective of what’s played through them. Fundamentally, it’s down to individual taste. Personally, I tend to favour the ‘American sound’, such as the classic Fender amps, rather than the stalwarts from this side of the Atlantic, typified by Marshall, Vox and Orange. Gibson, surprisingly, has never been as commercially successful at making guitar amplifiers, leaving opportunities for other US makers such as Mesa/Boogie and Peavey. How about some other classic names from the past, such as WEM, H/H, Roland, Laney, Sound City and Hiwatt, amongst others – some still going while others are history. The differences between the various brands are, unsurprisingly, manifold. Nowadays there is a plethora of amps ranging from the far eastern mass-produced to the US and UK boutique builders. Ultimately, it is down to individual taste and, perhaps, what guitar you play. For info, I currently use a vintage Music Man (click here to see the amp feature…) and a modern Cornford Carrera combining the best of US and UK heritage. It is with much sadness that neither are still in production. I recently purchased the wonderful mid-70s vintage Music Man 210 ‘sixty-five’ amp to use as my main amp of choice. This means that some tranny practice and studio gear may have to become ex-loved CRAVE items soon.

Over time, there have evolved recognised and well-accepted guitar/amp pairings, such as the humbucker equipped Gibson Les Paul through a Marshall amp, or the single coil loaded Fender Stratocaster through a Fender amp. However, there are now so many different permutations that provide limitless possibilities for creating one’s own personal signature sound. Why so many guitarists strive to recreate the sound (and style) of others rather than seek a unique, individual signature of their own is probably best left for another debate. For practicality, modern valve amps are safe, reliable and sound great, while digital alternatives give a very good impression of many classics that, let’s face it, most of us will never get to play (let alone own) for real, so let’s not get too snooty. Whether you go for a traditional approach or you adopt a mix-and-match attitude to differentiate your sound, you can experiment to your heart’s content. There is no right or wrong, just what inspires your creativity. That’s the joy of our beloved hobby.

Then, in addition to amplification, there is an abundance of effects units (a.k.a. FX, stompboxes, pedals, etc.) from the mass-manufactured giants to the tiny custom-built independents. The choice is plentiful. The history of stompboxes really started in the 1960s with the fuzz and wah-wah, and has flourished ever since. Now, you can create almost any live or studio sound that you want, from subtle enhancement to unrecognisable noise sculpting. Take your pick between analogue, digital or hybrid, whatever takes your fancy. Personally, I have a soft spot for 1970’s lush vintage analogue Electro-Harmonix effects pedals, such as the Big Muff Pi, Memory Man and Electric Mistress. For modern effects, I generally use Boss and Line 6 units. So much choice, so many opportunities, so little time to experiment. One could spend a lifetime exploring the creative tonal capabilities of effects alone without ever really listening to what the guitar itself can do. Again, it is worth investing in quality leads and power supplies to avoid degrading the magic of your performance.

One characteristic I’ve noticed is the traditionalism that extends from guitars to amps and effects. Many of today’s designs are either copies of, or are heavily influenced by, the past, for example emulating the classic Ibanez Tube Screamer, Dunlop Fuzz Face/Cry Baby or MXR Phase 90. Occasionally, there is genuine innovation; the Digitech Whammy pedal or Roland Loop Station spring to mind? I wait in anticipation for the ‘next big thing’ to challenge our usually conservative prejudices. In the meantime, there is a growing interest in acquiring vintage amps and effects to add to instruments and therefore (re)create the original setups heard on iconic stages and in countless studios for what seems a lifetime of great music, effectively reconstructing the soundtrack of our lives for new audiences. A subject for a future article.

CRAVE guitars are frequently played unamplified to get a feel for the way they resonate and respond to touch without any electronics. Other times, when the mood takes, it is fun just to pile on ridiculous amounts of modification and enjoy the sonic chaos created by rampant knob‑twiddling.
