July 2018 – A Potted History of the Guitar Part V

posted in: History, Introduction, Observations | 0

Hello again and welcome back to the latest, fifth, part in the long history of the guitar, abridged and serialised for your entertainment. After the lengthy but hopefully coherent, tome of last month, I promise this one is a bit shorter and focused back on whole guitars, for easier consumption.

If you wish to recap on previous articles before starting with this part, the previous articles making up the ‘Potted History of the Guitar’ series can be accessed here (each part opens in a new browser tab):

The previous article (Part IV) in the series covering the guitar’s evolution looked at some essential 20th Century technological innovations without which, the electric guitar and modern music would not have evolved within the context of our current civilisation.

The artificial increase in volume provided by the pickup, amplifier and loudspeaker was important to enable the guitar to be elevated from just an accompanying instrument to a lead/solo instrument. This significant expansion in functionality proved massively popular across most non-classical musical genres and would change popular music forever. Crucially, the electric guitar provided a springboard for the musical revolution that occurred from the 1950s, fuelled first by jazz and blues and then by country and the rock ‘n’ roll ‘explosion’. At the same time, post‑war economic growth and social liberalisation in most western societies provided a fertile environment within which the electric guitar and the music it influenced could flourish. Part V explores how those key innovations were first introduced to the guitar world and then became an integral part of what would eventually become today’s musical landscape.

There were considerable challenges in turning prototypes into successful working commercial products. One of the barriers was the capability to manufacture the various elements to consistent quality in large numbers at low enough cost to match supply with demand. Another potential inhibitor was to persuade exiting dealerships and traditional musicians to adopt the new technology. One strategy was to attract big name artists to not only endorse but also to be seen using them in live performance. All of these factors were important in helping to build and then sustain long‑tem interest.

Scientific and technological progress in the first half of the 20th Century, it seems, was inevitable and unstoppable. Guitar builders were taking massive leaps of faith and the risks were great. If the new‑fangled popular music turned out to be a temporary fad or the features offered didn’t catch the consumer’s imagination then all the investment in time, effort and money would be wasted. Manufacturers had to get their products ‘just so’ in a timely fashion, so there was pressure to adapt, get the balance right and to do so within a relatively short space of time.

In hindsight, the answers to these challenges seem relatively straightforward, although it may not have seemed so at the time. As mentioned briefly in the previous part of the story there were essentially two ways to migrate from an acoustic instrument to an amplified electric one…

The first method was, perhaps, an obvious incremental approach achieved by simply adding one of the new‑fangled pickups to an existing hollow‑body acoustic instrument. The modified acoustic guitar could then simply be connected to a portable valve amplifier and speaker. This would be an attractive approach for many well‑established jazz/dance band musicians. However, the potential of this solution – at least initially – was limited by fact that that all that was happening was simply electrifying acoustic guitars. Not surprisingly, it worked for companies already producing credible archtop acoustic guitars, including, for example, Gibson.

The second method was to take a more radical approach and invent an entirely new type of instrument designed from scratch. This was technically far more difficult at the time and carried no guarantee of success. However, a bespoke approach was seen as less of a compromise and more a means of going straight to a visionary objective in one step, as well as doing so quickly without being constrained by anything that had gone before. The forward‑looking pioneers in this field believed that a purpose‑built electric guitar would appeal to a completely different audience and were prepared to take the massive risk of alienating the current generation of risk‑averse musicians in order to grow a fresh following for the new generation of guitars from a low base.

Arguably, both ways were important and both were needed in order to refine the inventions and for the best of both worlds to converge. Without these pioneering efforts, we would not have the diverse range of electric guitars (and other instruments) we have today. The following sections take a brief look at what happened to each of these seemingly opposing strategies and how successful they really were.

Generally speaking, the development of acoustic guitars had taken different courses on the eastern and western sides of the United States, so perhaps it was not surprising that the developments leading to the electric guitar also followed a rough east/west geographical split. In addition, the routes taken to get to the nirvana of the electric guitar were fundamentally different. While there were many inventors, engineers and entrepreneurs working on similar projects, this part of the story focuses on two key enterprises based in Michigan and California during the 1930s. The pace of innovation that occurred in the wake of WWII, through the late 1940s and into the 1950s will be the focus of the next part of the series.

Amplified Archtop Guitars

On the eastern(‑ish, actually the mid-west) side of America, Gibson being Gibson, felt that they were in control of their own destiny. They were intent on doing things their way and in their own time. Although Gibson was no stranger to innovation, perhaps predictably, they chose the ‘safe’ option, which was to add an electromagnetic pickup to their successful range of existing archtop guitars and then take it from there. This was seen as a simple, effective and relatively painless way of making the transition for an existing largely conservative and loyal user base to the new platform. Professional musicians, perhaps conscious of retaining their reputation and credibility could keep the look, feel and timbre of their existing instruments and just plug them into an amplifier to make them louder. While the approach was successful, as we now appreciate, the seemingly straightforward act of electrifying an acoustic instrument isn’t always ideal. Many initially sceptical professional musicians were, however, persuaded to embrace incremental change. They could retain their trusty, mostly expensive, high quality acoustic archtop guitars and also keep their expectant audiences happy.

While their upstart competitors on the west coast may have beaten Gibson to the starting gate technologically (see below), the Hawaiian lap steel market was finite and Gibson was intent on occupying what they saw as their rightful territory in the centre ground. Gibson founder, Orville Gibson had passed away in 1918, long before Gibson electric guitars became a reality. One wonders what Orville would have thought and, perhaps more intriguingly, done if faced with the same set of circumstances.

While acoustic engineer Lloyd Loar was employed at Gibson, he had experimented with electrostatic pickups in the early 1920s, although not very successfully. It would, however, take Gibson another 10 years to make their breakthrough. It fell to Gibson employee, Walter L. Fuller, who had joined the company in 1933 who was responsible for finalising the design of Gibson’s first pickups used on their electric metal‑bodied E150 lap steel guitars, introduced in 1935. The electric E150 was, like the early Rickenbacher Electro lap steel guitars, constructed from sold aluminium. To help entice early adopters, the E150 was offered with a matching E150 amp.

A year later, in May 1936, Gibson introduced their first ‘Electric Spanish’ (ES) model, the hollow body archtop ES‑150. While some may dispute the circumstances, the Gibson ES‑150 is historically significant in that it is generally regarded as the first commercially successful production electric guitar. The Gibson ES‑150 employed the same pickup as used in the previous year’s E150 lap steel. Two large 5” bar magnets were hidden under the top of the guitar, as can be seen by the triangle of mounting bolts, while the hexagonal pickup with its distinctive ‘blade’ polepiece was visible, mounted near the neck. The output jack socket was positioned unobtrusively on the side of the guitar’s lower bass bout. Otherwise, the ES‑150 was a relatively unremarkable example of familiar archtop jazz guitar design of the 1930s. Interestingly, the ES‑150 wasn’t a replacement for another Gibson model; it was a new introduction, supplementing existing instruments.

Like the E150, the ES-150 was sold with an accompanying EH‑150 amplifier and cable. The ‘150’ of its name derived from the guitar’s introductory price of $150.

Importantly for Gibson, the ES‑150 was endorsed by acclaimed jazz guitarist Charlie Christian (1916-1942), which helped to popularise amplified archtop guitars not only for rhythm work but also for lead/solo playing. The distinctive black and white hexagonal pickup used in the ES-150 is still known today as the ‘Charlie Christian’ pickup and is held in high regard by aficionados, despite being very low‑powered in its original form. After 1938, Gibson redesigned the pickup so that it was more powerful – it had a notch in the polepiece below where the wound ‘B’ string would go, in order to balance the output across all 6 strings. A third variation of the pickup appeared on Gibson ES-250s from 1939, perhaps indicating that development of the pickup was ‘work‑in‑progress’.

By the end of the 1930s, Gibson’s Walter Fuller was experimenting with Alnico (aluminium, nickel and cobalt) alloy magnets in pickups. Various guitars of the early 1940s featured early versions of what would become one of Gibson’s most famous pickups, the P90. These developmental designs, used on Gibson ES-250 and ES-300 guitars, were a far cry from the familiar P90 pickups that would follow. Another early version of the P90, called the P-13, appeared on Mastertone Electric Spanish Guitars from 1940, a budget brand owned by Gibson.

Between 1943 and 1945, a substantial proportion of Gibson’s manufacturing capacity was re‑focused on supporting the American war effort. Supply of materials and tooling caused a temporary hiatus in America’s pickup, guitar and amplifier development, not only for Gibson but also for all manufacturers in the industry.

It wasn’t until 1946 that Gibson introduced the fully‑fledged single coil P.U.90, now known simply as the P90, on their ES-150 and ES-300 archtops. The P90 has become one of the company’s most famous and highly respected pickups, and a design that has endured almost unchanged over many decades. The P90 pickup was important to Gibson as it really established Gibson’s dominance in pickup design prior to the introduction of humbucking pickups. The successful P90 became a standard and effectively replaced Gibson’s earlier pickup designs. Although Gibson’s humbucking pickups were intended to replace the P90 in the 1950s, the P90 remains in production today as Gibson’s predominant single coil pickup, testament to the quality of its original design.

Once the concept of electric archtop guitars had been broadly embraced by enough mainstream guitarists, Gibson extended the use of pickups to other guitars. In 1949, Gibson released the ES-175. Like the ES‑150 before it, the model was named after its introductory price of $175. This model was important in the historical timeline because it was designed from the start to be an electric guitar, rather than an acoustic guitar with a pickup. It was also considered a cheaper guitar than Gibson’s upmarket archtops like the acoustic L5 and Super 400. Unlike its predecessors, the ES-175’s all‑hollow body was constructed from laminated boards rather than solid wood and it was the first Gibson to feature a pointed Florentine cutaway. Initially, the ES-175 came with one and then two P90 single coil pickups. By 1957, Gibson switched to their new humbucking pickups to the E‑175.

Following on from the ground breaking ES-150 and the ES-175, Gibson revisited an earlier classic creation by introducing the luxuriously appointed L5CES in 1951. The new model was based on the preceding L5 originally designed by Lloyd Loar in the 1920s. The L5CES was aimed squarely at the high end and was designed to provide the best of both worlds for discerning professional musicians. The ‘C’ stood for the single ‘cutaway’ body comprising spruce top and maple back and sides. The model was produced initially with a smoothly rounded Venetian cutaway and a pair of P90 single coil pickups, followed later by a sharply pointed Florentine cutaway and humbucking pickups. The ‘ES’ continued the ‘Electric Spanish’ nomenclature of other models. By using 2 pickups, the L5CES was intended to be used both acoustically and electrically. A notable user of the electric L5 was Scotty Moore who worked with emerging rock ‘n’ roll singer, Elvis Presley in the 1950s. There were a number of variations on the theme, including the thinline, short scale Byrdland and in the 1970s, Gibson even introduced a solid body version of the L5, called the L5S.

In 1955, Gibson introduced their first production humbucking pickup, designed by Seth Lover. Early versions of the Gibson P.U.490 humbucker have become known as PAF (Patent Applied For) pickups, while ones produced after their patent was awarded in 1959 are known as ‘Patent No.’ pickups. Succeeding versions of the Gibson humbucker right up to the current day have built on the foundations of these early, now legendary, pickups. As they had done in the 1930s, Gibson launched their new pickup first on lap steel guitars in 1956 before phasing them in to replace P90s on the aforementioned ES‑175.

It wasn’t long before PAF humbuckers were used on many Gibson guitars. Unsurprisingly, they also began to appear in the company’s (relatively) new solid body gold top Les Paul Model and black Les Paul Custom guitars from 1957 as well as on the all‑new semi‑acoustic ES‑335 from 1958. However, that’s getting ahead of this particular part of the story. Fortunately for Gibson, their humbucking pickups proved highly successful across all types of electric guitar and have long since become an industry standard, with many 3rd party pickup suppliers creating their own versions. Even the original Charlie Christian pickups are now being replicated for enthusiasts of the unique sound they produced.

There have, perhaps obviously, been plenty of other electric archtop guitars over the intervening years from a wide range of manufacturers across the globe. While this part of the story recognises this diversity, it cannot do justice to the proliferation of instruments on the market today. Needless to say, many of today’s designs have been inspired by the few milestone instruments mentioned here. Arguably, progress would have taken place anyway, even without these key instruments. However, the guitars covered above are particularly notable in historical terms not necessarily because they were the first or the best but because of the part they have played in the overall heritage.

Again in hindsight, the addition of one or more pickups to an existing acoustic guitar may seem to be an obvious option. However, at the time, it was a significant development by a company that was known for combining innovation with traditionalism. It was a strategic decision by Gibson that achieved that clever balancing act, innovating while preserving their reputation and sustaining their user base during a time of major industry and social change.

When the time came to introduce their own range of solid body guitars in the early 1950s, Gibson already had plenty of experience under their belt to make informed decisions about what would and what wouldn’t work. It is not surprising that other manufacturers followed suit and the electric archtop guitars became mainstream until the 1950s.

The electric archtop guitar proved extremely popular with traditional guitarists looking to continue using archtop jazz guitars while also enjoying the benefits of greater volume provided by amplification. After a commercial nadir in the late 20th Century, archtop electric designs have also proved exceedingly dependable and many models remain popular to the current day, and will probably now endure well into the instrument’s future.

 

The Early Solid Body Electric Guitar

Possibly the main individual associated with the rather awkward birth of the electric solid body guitar was Adolph Rickenbacher (1886‑1976). Shortly after he was born in Basel, Switzerland, Richenbacher emigrated to America in 1891 with relatives following the death of his parents. After settling initially in Wisconsin, Adolph moved to California in 1918. In 1925, he set up the Rickenbacher Manufacturing Company, a tool and die business manufacturing metal and plastic products in Los Angeles.

To begin with, Rickenbacher spelled his family surname with an ‘h’, rather than the ‘k’ we are familiar with today. Rickenbacher later changed his surname, partly to ‘Anglicise’ it and partly to capitalise on the fame of his cousin and WWI flying ace, Eddie Rickenbacker.

Alongside Rickenbacher, the other key person was none other than George Beauchamp, the Texan Vaudeville entertainer and inventor who had already played such a major part in the development of resonator acoustic guitars with the National String Instrument Corporation in the 1920s. In addition to pioneering resonator guitars (see Part III), Beauchamp had been experimenting with pickups and amplified instruments since the mid‑1920s but with little success (see Part IV).

Perhaps ironically, during the late 1920s, Rickenbacher’s company was manufacturing metal resonator guitar bodies for National, so perhaps it is not surprising that Beauchamp and Rickenbacher’s paths should cross. Rickenbacher was even a shareholder in National. According to some commentators, it was Beauchamp’s involvement with Rickenbacher that possibly precipitated the former’s ultimate departure from the newly merged National Dobro Corporation in around 1934.

Beauchamp’s quest for greater guitar volume had led him to explore the idea of using an electromagnetic pickup to create a signal and an amplifier to produce volume. Like many before him, Beauchamp was driven to prove the concept in a practical way and he was largely successful. Beauchamp had started designing pickups and ideas for an electric guitar while still at National and in collaboration with another National employee, Paul Barth. Beauchamp and Barth’s first successful pickup design comprised a pair of U‑shaped magnets arranged in a ‘horseshoe’ shape that housed the pickup’s wire coil and surrounded the guitar’s strings.

In October 1931, Rickenbacher, Beauchamp, Barth and a number of others became business partners and founded the Ro‑Pat‑In Corporation (short for Electro‑Patent‑Instruments), based in Los Angeles. Ro‑Pat‑In’s stated goal was to produce fully electric musical instruments. Their prototype Hawaiian electric guitar from c.1931 exhibited many of the features of the eventual production model, although it was mainly constructed from wood. This was not an acoustic guitar in any shape or form, so it had to function as an electric instrument from the outset.

Ro‑Pat‑In became the first company to design and manufacture a production solid bodied electric guitar in 1932, way before Gibson. Finally, albeit in embryonic form, the fully electric guitar had finally arrived. These early guitars were, perhaps unkindly, nicknamed ‘frying pans’ because of their distinctive shape, comprising small circular bodies, long necks and all-metal construction. The guitar comprised a circular cast aluminium body and neck and incorporated the all‑important ‘horseshoe’ pickup and a volume control.

Wisely, Ro-Pat-In changed its unwieldy name to Electro String Instrument Corporation in 1933. Confusingly, early instruments appeared with the ‘Electro’ (and even ‘Elektro’) name. Even more confusingly, the company used the Rickenbacher spelling inconsistently until it finally became Rickenbacker from around 1950.

Following the name change, the ‘frying pan’ became the Rickenbacher Electro A-22. The profile of the instrument was heightened by steel guitarist Jack Miller who played a ‘Frying Pan’ with Orville Knapp (1904-1936) and his orchestra from 1934. Although he was little‑known at the time, Miller may possibly be able to lay claim to being one of the first artists to popularise the electric guitar.

As previously covered in Part IV of the story, Beauchamp’s 1934 patent application for an ‘electrical stringed musical instrument’ incorporating an electromagnetic pickup was finally awarded in April 1937. The intervening 3‑year period allowed enterprising competitors to take advantage of the new technology and create their own versions. Rickenbacher made a conscious decision not to defend their patent in the courts, thereby effectively opening up the market to competition.

Aluminium often caused tuning problems under demanding stage conditions, so Rickenbacher also experimented with other materials, including plastic and wood. From 1935, Electro released the influential Model B Hawaiian lap steel guitar. The Model B was notable for being made from cast Bakelite, a form of synthetic plastic invented in 1907 by Belgian-American chemist Leo Baekeland (1863-1944) in New York. Model B guitars were originally produced with a single volume control and five decorative chrome panels before models from the late 1930s featured volume and tone controls with white enamelled panels.

Richenbacher and Beauchamp recognised that the market for lap steel guitars was relatively small and there were other opportunities to be exploited. From 1932, Rickenbacker also went on to design more traditional ‘Electro Spanish’ guitars with conventionally‑shaped acoustic wood bodies, f‑holes, a slotted headstock and neck to body join at the 14th fret. By 1935, guitarist and early endorsee Ken Roberts was honoured with a ‘signature’ model that had a neck to body join at the 17th fret, featured a vibrato tailpeice and was the first electric Spanish‑style guitar to have a 25½” scale neck.

Like the ‘frying pans’ before them, both the Model B and the Electro Spanish guitars used the distinctive ‘horseshoe’ pickup. In addition to guitars, Rickenbacher Electro used their expertise to develop other electric instruments including mandolins, violins, cellos and even a harp. To accompany their electric guitars and to make them usable, Rickenbacher Electro also produced guitar amplifiers.

Timing of these guitar developments wasn’t ideal and market conditions were challenging for Rickenbacher. Electro String’s instruments appeared shortly after the Wall Street Crash in October 1929, an event that initiated the Great Depression, a major worldwide downturn that persisted until the late 1930s. Coincidentally, during the 1930s, global political tensions started to increase culminating in the outbreak of WWII. Most of America’s industrial concerns were focused on supporting the war effort for several years and the ensuing recovery was slow. The impact on the uptake of electric guitars during depression‑era America was significant, particularly in rural areas. Despite the difficulties, Electro String Instrument Corporation persevered and had produced over 2,500 ‘frying pans’ by the time the company stopped making them in 1939.

After all his vision, ambition, creativity and drive, George Beauchamp became disillusioned with the direction in which things were moving and he left Rickenbacker in 1940 to follow other pursuits, including his passion for deep sea fishing. Beauchamp died of a heart attack while on a fishing trip near Los Angeles in 1941 at the age of just 42. Beauchamp was largely unrecognised at the time for his many significant contributions to guitar evolution.

Following Beauchamp’s departure, Rickenbacker continued making musical instruments until 1953 when he sold the company to Californian businessman Francis Cary Hall. After the sale, the Rickenbacker company embarked on a whole new era of guitar building and commercial success under Hall’s leadership. Adolph Rickenbacker died in 1976 as a result of cancer in California at the age of 89. The company he founded in 1931 continues to thrive and still bears his name (complete with its ‘k’) today as the Rickenbacker International Corporation (RIC).

End of Part V

This moment seems like another ideal stopping point, albeit covering a fairly short period of intense guitar evolution in the 1930s. Together, Gibson’s and Rickenbacker’s milestone innovations had bridged that all‑important gap between the guitar’s acoustic history and the introduction of commercially produced modern solid body electric guitars in the 1950s. From this watershed point on, nothing in the music world would ever be quite the same again.

It is the emergence of the modern electric guitar, and particularly the now‑familiar solid‑body guitar, as we know it that will be picked up in Part VI. The fascinating battle between industry stalwart Gibson and new‑kid‑on‑the‑block Fender was about to take place. Fender and Gibson started fighting for market supremacy in the 1950s and are still doing so today.

I hope you enjoyed this part of the guitar’s story and trust that you’ll come back for the next exciting instalment – same time, same channel, next month (hopefully!). Until next time…

May 2018 – A Potted History Of The Guitar Part III

posted in: History, Introduction, Observations | 0

Here we are again with the 3rd in a series of articles telling the long story of the guitar. Part I (→ read here) started over 3,500 years ago, emerging in the Middle East and gradually developing before dispersing across continental Europe and Asia. Eventually, the embryonic guitar found a home in Europe during the early Renaissance where it began to exhibit the characteristics and features that we recognise today. Part II (→ read here) expanded on the humble beginnings and evolved the acoustic instrument into a (generally) standardised form that we are familiar with, as well as focusing on some key 19th Century innovations in acoustic guitar design. This instalment looks at key 20th Century developments that will ultimately lead to the widespread introduction of the electric guitar.

The story from c.1900 is not only reasonably well-documented elsewhere but also fairly involved, so the pace slows compared to previous parts and also becomes richer in content. I would encourage anyone with a serious interest in guitar heritage to explore the hinterwebby thing for further information, along with all the usual caveats about the accuracy and believability of what’s out there.

Modern Era (1900-present)

At the end of the 19th and during the early part of the 20th Century, before the introduction of the electric guitar, musicians sought ever‑louder instruments, leading to various creative adaptations to the basic construction of the acoustic guitar. While the acoustic guitar continued to be popular for classical and traditional folk music, many guitarists were struggling to be heard as the trend for ensemble, ‘big band’ or swing orchestras became popular at the time. The issue with volume in a group context meant that the guitar essentially became consigned to a rhythm, rather than lead role, especially when competing with percussion and horns. In order to adapt to demand, a radically new approach to guitar design was needed. Thus, the fundamental divergence from traditional nylon strung classical and steel-strung acoustic ‘folk’ guitars had begun.

Guitars at the beginning of the 20th Century were, though, still entirely acoustic instruments. However, two key innovations were about to take place in America that would bridge the gap from acoustic to amplified electric guitars, which would began to appear in the 1930s. The first development involved the emergence of the acoustic archtop guitar on the east coast while, on the west coast, the second invention to appear was that of the resonator guitar.

Guitars weren’t the only ubiquitous chordophones at the start of the 20th Century; far from it. The mandolin, banjo, harp and violin also had periods of great popularity and fashion. However, it was during the first quarter of the 1900s that the guitar started its elevation from just another part of a band or orchestra into being the pre‑eminent instrument it is today. Arguably, in addition to the standardisation of classical and steel strung acoustic guitars, it was the introduction of archtop and resonator guitars that contributed towards that success. As is often the case in these matters, the path to success was more complicated than it seems at first and it would be far from a smooth transition with many pitfalls along the way.

Acoustic Archtop Guitars

The acoustic archtop guitar incorporated some of the basic components of the steel string acoustic guitar with a body style that bore some design and construction similarities with classical orchestral stringed instruments. An archtop guitar may be defined as, a stringed musical instrument with a convex curved top, formed either by carving a solid piece of tone wood or by heating a sheet of laminated wood in order to  mould it into the curved shape.

Most flat top acoustic guitars up to the end of the 19th Century used a single integrated bridge/tailpiece mounted to the surface of the top soundboard, meaning that the strings exert not only significant horizontal pull but also lift because of torque. In order to prevent the bridge from lifting and/or twisting, particularly with the greater tension required by metal strings, the thin flat acoustic soundboard required strong internal bracing. Heavily braced tops had the effect of reducing resonant vibrations and inhibiting overall volume. One solution was to make guitars bigger, an approach used by C.F. Martin in the 1930s with the introduction of the company’s sizeable X-braced D-series dreadnoughts, as covered in the previous part of this series of articles. Archtop guitars took an entirely different approach.

Unlike acoustic guitars, most orchestral stringed instruments had a long history of using a carved arched top featuring a separate moveable bridge and fixed tailpiece. The main advantage of using separate structures is that they serve different functions. The non-adjustable tailpiece is used to anchor the strings at that end of the instrument and deals only with the longitudinal stresses caused by string tension. The separate ‘floating’ bridge (meaning that it was not fixed and could be repositioned if needed) supports the strings and is used only to control string height (action) and intonation. The solid carved top of the soundboard was arched upward, as on a violin or cello, in order to counteract the downward pressure that the strings exerted on the bridge, thus providing a stable and resonant structure. The major benefit of this type of design is that it needs less internal bracing which allows the instrument’s soundboard to vibrate more freely, thereby producing a noticeably louder sound.

It was therefore not really surprising that, at some point, enterprising guitar builders would seek to exploit some of the characteristics of other instruments and incorporate the best of these into guitar design. While there may have been numerous examples of experimentation before this time, the enduring convergence of classical stringed instrument construction and acoustic guitar design resulted in the advent of the acoustic archtop guitar from the beginning of the 20th Century.

The Rise of Gibson Guitars

Although not the only innovator in guitar design at the turn of the 19th Century, certainly one of the key pioneers that popularised early archtop guitars was American luthier Orville H. Gibson (1856-1918), who was born in Chateaugay, New York. Gibson started making mandolins in his home workshop in Kalamazoo, Michigan in 1894 as ‘O.H. Gibson, Manufacturer, Musical Instruments’.

Gibson himself was, by all accounts, somewhat unconventional, being described as an obsessive, eccentric genius as well as an extreme perfectionist. He apparently held other, more traditional, instrument makers of the time in contempt and he was determined to do things differently and in his own way. Orville Gibson, the person, remains somewhat of an enigma and appears to have suffered from mental illness throughout his life, spending several periods in mental institutions before his death in a psychiatric asylum in New York.

Gibson started out by adapting European violin designs for use in mandolins and then, subsequently, guitars. By 1897, Gibson had made his first hollow archtop guitar with a relatively thick carved solid wood top, back and sides, cello style tailpiece, floating bridge and steel strings. His early designs retained the traditional acoustic guitar sound hole, although oval in shape. He used spruce wood for the top for its resonance and maple for back and sides for strength and density. Unlike traditional flat top acoustic guitars of the time, Gibson’s archtop guitars did not use internal bracing, as he felt this would hamper both volume and tone. When played hard, Gibson’s relatively un‑stressed design was more capable of projecting the loud, bright and ‘percussive’ acoustic volume that guitarists were seeking at the time.

Orville Gibson submitted his only patent application in 1895 for an archtop mandolin design (also applicable to the guitar), which was granted by the U.S. Patent Office in February 1898. The patent covered archtop construction comprising carved, tops and sides cut from solid wood, rather than the acoustic guitar’s braced flat top and bent wood sides. While earlier guitar/mandolin patents by James S. Back in 1893 and A.H. Merrill in 1896 may lay claim to the first archtop designs, it was Gibson that converted his own visionary concepts into a successful business enterprise.

On 11 October 1902, Orville Gibson, along with five local business partners founded the Gibson Mandolin-Guitar Manufacturing Co. in Kalamazoo. The company soon started building archtop guitars using the techniques Gibson had patented for the mandolin. However, Gibson was paid a $2,500 lump sum and monthly income to step back from day-to-day business where his overt, pedantic idiosyncrasies tended to affect production.

While the Gibson F-2 mandolin was a major milestone in the instrument’s history and is now considered a classic landmark design, mandolins generally were beginning to lose favour with musicians. In addition, Gibson had initially followed the trend for tenor banjos in the late 1910s before guitars became the mainstay of the business. Gibson was also known to make complex but not widely used harp guitars, such as the Style U.

Gibson’s Style 0 archtop guitar design proved better suited to the jazz and swing orchestras of the time than the flat top acoustic guitar. As a result, Gibson guitars became very popular in the early part of the 20th Century up to the 1920s, particularly amongst the jazz fraternity. The Style 0 archtop, which retained the oval sound hole beneath the strings, is often referred to as the direct precursor to the archetypal jazz acoustic archtops that followed. The hand‑carved guitars were, however, very resource intensive to build, so supply fell short of demand and there was a growing need for an instrument that was quicker, easier and cheaper to build.

Orville Gibson finally left the company he founded in 1916 to live in upstate New York until his death in 1918 at the age of 62.

In the same year, 1918, composer, musician and engineer, Lloyd Loar (1886-1943) was hired by the Gibson company as acoustic consultant and advisor. After a break to entertain WWI troops in Europe, Loar re-joined Gibson in 1919. Loar went on to design many of the company’s new instruments in an attempt to turn around disappointing sales. While Loar wasn’t a luthier by trade, he led a design and construction revolution at the company during the 1920s, growing the company’s enviable reputation for building fine professional guitars, mandolins and other stringed-fretted instruments.

One of Loar’s first and best‑known guitar designs, released in 1923, was the Gibson L5 ‘Master Model’. The L5 is widely recognised as the first commercially produced ‘jazz’ guitar. In 1923, the L5 featured all the fundamental characteristics that we recognize in a ‘jazz’ guitar; a carved archtop fully hollow body, separate tailpiece and floating bridge, etc. It was also the first commercial archtop guitar to employ f‑holes that are now synonymous with the style of guitar. The L5’s neck incorporated other innovations, including an adjustable truss rod, designed to counteract string tension, and the body used an adjustable bridge to set the height of the strings above the fingerboard. These key improvements enabled guitars to become more streamlined and therefore easier to play. The L5 was a trendsetter and gained a strong following in the jazz community. Early adopters included the popular guitarist Eddie Lang, comedian/singer George Gobel, and jazz virtuoso guitarist Wes Montgomery.

The L5 is now considered to have been pivotal in acoustic archtop guitar design. As if to evidence its standing, the perennial L5 remains in production well into the 21st Century, proving the soundness of Loar’s original concept. Lloyd Loar did not stay long at Gibson, leaving in 1924. During the 1920s and 1930s, Gibson became the leading manufacturer of archtop guitars. The perennial Gibson L5 will resurface again later in the guitar’s story.

Gibson archtop guitars remain in production today, including some faithful reproductions and improvements on the classic designs that began in the 1920s.

The Competition

Gibson wasn’t alone in the market and its competitors included Stromberg, Epiphone, Gretsch and Hofner were also making high quality instruments. In addition, from 1932, American luthier John D’Angelico (1905-1964) started producing very fine archtop guitars from his workshop in New York City. In 1965, his apprentice of 12 years, Jimmy D’Aquisto (1935-1995) took over D’Angelico’s work and continued to produce fine acoustic archtop guitars after his master had passed away. Original examples of these guitars are seen by many to represent the pinnacle of the jazz guitar era.

In order to provide ever‑increasing demand for volume, the size of archtop guitar bodies increased from the 16” L5 up to 18” or even 19” measured across the lower bout. Gibson’s reaction to competition was to produce one of the brand’s most famous archtop guitars, the classic Super 400 in 1935.

Arguably, classic archtop guitar designs provided a strong link between traditional steel strung acoustic guitars, through hybrids (electric archtops) to the emergence of later solid body electric guitars. The introduction of electric archtop guitars in the mid‑1930s enabled the transition from acoustic to electric guitars and is covered later in the story.

With the widespread uptake of electric guitars allied to the massive growth of blues and rock ‘n’ roll music in the 1950s, the pure archtop guitar with its strong jazz association struggled to remain popular. Manufacture and sale of archtop guitars fell dramatically and suffered a nadir in the 1990s. However, in the 21st Century, many guitarists are rediscovering the aesthetic and sonic qualities of classic ‘jazz boxes’. Sales of new archtop guitars have picked up due to a new generation of musicians either seeking an alternative to mainstream instruments or wishing to recreate the sights and sounds of the past with a degree of authenticity.

Many current‑day archtop guitars incorporate pickups to make them more usable in contemporary situations. Modern manufacturing processes including CNC machines used to carve the tops also help to reduce cost and make archtop guitars relatively affordable. Alternatives to solid wood are also abundant today, including the use of formed laminates to create the curved tops.

Acoustic Resonator Guitars

While the concept of archtop guitars was one response to the need for louder instruments a discrete branch of guitar evolution was taking place on the west coast of the U.S.A. In the time before amplified guitars, manufacturers had to respond to the demand for greater acoustic volume during the golden ‘jazz age’ of the ‘roaring twenties’. This particular alternative to the archtop guitar is broadly categorised as the resophonic or resonator guitars. Hereafter they are called simply resonator guitars for brevity.

A resonator guitar in this context is still a hollow acoustic guitar. Resonator guitars differ from previous designs because of the way that mechanical string vibrations are transferred not to the guitar’s sound board but via the guitar’s bridge to one or more spun metal cones incorporated within the guitar’s body. It is these resonating metal cones that produce a louder sound than the traditional wooden sound boards of flat top or archtop acoustic guitars. Musicians also favoured the flexibility of resonator guitars over banjos, which were popular in the early part of the 20th Century.

The unique construction of resonator guitars also produced a very distinctive thin, bright, metallic sound with little sustain, very different from other acoustic guitars. The distinctive resonator sounds were adopted by blues, bluegrass and country guitarists of the time and have produced many of the characteristic sounds of rural American music over many decades, especially when played with a bottleneck slide. It should be noted that, while resonator guitars are widely associated with the blues, and particularly with Mississippi delta blues guitarists, they have been used in a diverse range of musical genres.

General resonator guitar designs tend to fall into two separate types: square-neck Hawaiian lap steel resonators tend to be played horizontally with a slide and round‑neck resonators that can be played either horizontally, lap-steel fashion, or conventionally. The height of the strings above the fingerboard varies considerably depending on whether the guitars are used for slide, hybrid or regular fingerstyle use. In addition to lap‑steel and Spanish‑style guitars, resonators have been used in many diverse instruments including, ukuleles, banjos, basses and mandolins. Resonator guitars remain popular today, principally for their unique sound and the musical styles they inspired. English guitarist, Mark Knopfler’s iconic 1937 National Style 0 resonator was famously featured on the sleeve of their classic studio album, ‘Brothers In Arms’ (1985).

Some famous guitarists are associated with resonator guitars, including Tampa Red, Son House, Bukka White, Bo Carter and Blind Boy Fuller.

The Rise of National and Dobro Guitars

Probably, the most significant contributor to the development of the resonator guitar was a Slovakian immigrant to the U.S., John Dopyera (1893–1988). The Dopyera family moved to California in 1908 and John followed in his father’s footsteps, starting a business in the 1920s making and repairing musical instruments.

The crucial catalyst in resonator progress was provided by a Texan Vaudeville performer and musical experimenter, George Beauchamp (1899-1941). Once Beauchamp (his surname was pronounced ‘Beechum’) had moved to California, he approached John Dopyera in 1925 to design a guitar loud enough for use in a dance orchestra. Beauchamp had seen examples of some sort of external megaphone‑style horn arrangement to project a guitar’s volume. Dopyera’s initial prototype, involving a stand‑mounted amplifying horn proved far too bulky and was considered a failure. Undaunted, Dopyera and Beauchamp’s creative solution was to invent the resonator guitar.

Recognising the potential of the new resonator guitar design, John Dopyera and George Beauchamp founded the National String Instrument Corporation in 1927, based in Los Angeles, California to manufacture resonator guitars and other instruments under the National brand.

National’s first major instrument was a metal‑bodied guitar using three inward‑pointing suspended spun aluminium cones connected by a metal T‑shaped bracket to the bridge. The arrangement was, perhaps unsurprisingly, called a ‘Tricone’. String vibrations were acoustically amplified by the cones, acting like passive loudspeakers, giving the guitar its distinctive resonator sound. Dopyera filed a patent application for the Tricone design in April 1927, granted in December 1929. The ground breaking early National Tricone resonator guitars from the late 1920s are now highly collectable. The first engraved metal bodies were made of copper and zinc alloy (often called ‘German silver’ or ‘white brass’) before changing to traditional brass which was cheaper and more plentiful, then finally to steel.

1939 National Tricone Resonator

John Dopyera was concerned about the manufacturing cost and retail price of the complicated tricone design and proposed a cheaper, simpler single cone alternative. When the new design was presented to National’s board, it was rejected. His new single-cone design comprised an arrangement where the strings passed over a bridge that sat on a small circular wooden mounting disc (called a ‘biscuit’) that was in turn attached to the apex of the inward‑pointing spun metal cone. Although it wasn’t taken up at the time, Beauchamp, through National, went on to patent Dopyera’s single cone ‘biscuit’ resonator design, filed in March 1929 and granted in June 1931.

John Dopyera, having become frustrated by National’s internal politics, left the company in 1928. Crucially, to keep his options open, Dopyera remained a major shareholder in National. Along with his four brothers (Rudy, Emile, Robert and Louis), John Dopyera founded the Dobro Manufacturing Company to compete with National. The Dobro name comprises the ‘Do’ from the family’s surname and ‘bro’ as a contraction of ‘brothers’. The term ‘dobro’ has over the years come to be used as a generic term in common parlance when talking about single resonator guitars. Conveniently, and perhaps intentionally, the word dobro also means ‘good’ in Slovakian, leading directly to the company’s early motto using a play on words, “Dobro means good in any language”.

As National owned the resonator patents to-date, early Dobro resonator guitars had to differ from the single cone design made by National. The new Dobro guitars used a wooden body and a single inverted (outward‑facing) resonator cone with guitar strings passing over a bridge attached to an 8-legged cast aluminium ‘spider’ (resembling a spider’s web) that in turn was attached to points around the edge of the spun metal cone. Unlike the National single cone design, the Dobro cone projects outwards, thereby increasing volume. Dobro filed a patent in February 1932 for Rudi Dopyera’s resonator design, which was granted in February 1933. National objected to Dobro’s resonator design, resulting in several contested law suits between National and Dobro, which lasted for several years.

The advantage for guitarists was that the Dobro was both louder and considerably cheaper than the complex and costly National Tricone design. In addition, Dobro cleverly licensed their designs to brands such as Regal to extend their reach into an eager customer base. National responded to competition from Dobro by introducing their lower cost resonators, the Triolian in 1928 and Duolian in 1930. Also in 1930, National released their nickel-plated, steel‑bodied, round necked Style 0 resonator guitars, which featured Hawaiian scenes sandblasted into the guitar’s finish and are now considered iconic. In an attempt to cover all bases, both companies also produced resonator mandolins.

In 1932, with National in financial difficulty, the Dopyera brothers secured a controlling interest in both National and Dobro companies. The companies subsequently merged in 1934 to form the National Dobro Corporation, thereby ending the feud and eliminating the fierce competition between the two. Beauchamp was fired by the new company for his involvement with newcomers, Rickenbacker, who were developing new ideas for electric guitars. The National Dobro Corporation moved operations to Chicago in 1936 where it manufactured resonator guitars until it ceased production in 1941, shortly after America entered World War II. Aluminium was needed to support America’s war effort, making the raw material for resonator cones scarce and the demand for tooling machinery high.

Post-War Resonator Guitars

The remnants of the pre‑WWII National Dobro Corporation were later reorganised to become Valco in 1942, which eventually reintroduced resonator guitars under the National brand in the early 1960s. American company Mosrite bought the Dobro brand in 1966 before going bankrupt themselves in 1969. A new company, National Reso‑Phonic Guitars was formed in 1989, based in California, to produce resonator guitars based on original pre‑war designs as well as some all-new designs, including electro-acoustic resonator guitars.

Taking a different direction altogether, Emile and Rudy Dopyera formed the Original Musical Instrument Company (OMI), based in California in 1967 to make resonator guitars using the brand name Hound Dog. In 1970, OMI secured the Dobro brand name from the bankrupt Mosrite, which meant the Dopyera family could once again manufacture Dobro guitars using their original name. OMI was subsequently acquired by The Gibson Guitar Corporation in 1993 and they currently produce Dobro branded resonators, including Dobro Hound Dog budget models through their Epiphone operation in China. In an attempt to secure the heritage, Gibson has stated that they will defend their exclusive right to use the Dobro name.

While many variations of resonator guitars have been manufactured by a large number of companies over the years, National and Dobro, along with Dobro-licensed Regal, are the names most associated with pre‑WWII resonator production. The influence and legacy of these brands is significant in historical terms and 21st Century popularity of resonator guitars suggests that they are here to stay with a bright future ahead. Many modern resonators now incorporate either electro‑magnetic or piezo‑electric pickups, enabling them to be amplified, just like other electric guitars, while retaining their distinctive acoustic tone. Given the reason why resonators were invented in the first place – to increase acoustic volume – the concept of electric resonators seems a touch ironic today.

End of Part III

I will stop at this juncture, just before the dawn of the electric guitar. In terms of the overall amount of material, Parts I-III cover about half the story I have to tell.

I must mention that this part of the story proved particularly convoluted and I apologise if it comes across confusingly. It was a major challenge to untangle the web of misinformation and distil a meaningful chronological narrative. I hope that you are able to make some sense of the various interweaving threads. The information for the next part proved even more tortuous and I’m still trying to simplify and condense it for the serial article format. As with previous parts, I am happy to amend any factual errors that may well have crept into the timeline thus far.

Before we get back to the next decisive milestones in the guitar’s long story, Part IV will be both a temporary and necessary diversion from the core subject matter. The next episode focuses on two key innovations upon which the electric guitar is entirely dependent. You will have to wait a while to see what unfolds. There is a great deal of background material to wade through, so it will be a challenge to cut down the full version in order to keep the story moving. However, once that contextual reference material is in place, the modern electric guitar in all its splendour can finally be unleashed, hopefully in Part V and thereafter.

Thank you or looking in. As interesting as the story may be, it’s now time for me to stop typing and get back to more important matters; playing (vintage) guitars. Until next time…
