The Fender Twin amplifier is one of only a handful of amplifiers that has performed a major role in shaping the sound of the electric guitar. It is one of the true “game-changers”. Its legacy lives on through the artists who have used it to create some of the most iconic songs of our time.
That is as true today as it was back in the 1950s when the first versions arrived on the scene.
Whether you play a Fender amp or not, it is hard not to be inspired by what the Fender Twin, in its many guises, has achieved over the past 70 plus years. There probably isn’t a recording studio in the World that does not have at least one of these amps in its arsenal.
The Fender Twin was, and still is, a lot more than “just” an amplifier. It’s a tool that has helped musicians push their music to new and exciting levels.
The Birth of a Legend: The Fender Twin Guitar Amplifier
It all started in the early 1950s, when Leo Fender and his team of engineers were attempting to create a new and revolutionary type of amplifier. Their goal was to design an amp that was powerful enough to handle larger venues and that produced a clean, clear sound that would cut through the noise of a live performance.
After much experimentation, the first Fender Twin, the 5C8 model, was introduced in 1952.
First, it looked totally different to any other Fender amp we had seen before. Fender was now phasing out the “TV panel” look they had introduced in 1948. iThe Twin was a more streamlined design, still tweed-covered, in which the front grille ran from side to side to the inside edges of the cabinet. Fender described it as the new “Hi Fidelity” amp and this “wide-panel” design would be adopted for all the previous TV panel models.
The second big change was the size. This amplifier featured two 12-inch heavy duty Jensen speakers and boasted 25 watts of power, amazingly, making it one of the most powerful, and largest, amplifiers of its time. For the technically minded who love the amps from the 50s, here are the three models produced from 1952 to 1960.
The 5C8 model, originally called the “Twin 12 Amplifier” and “Twin 12 Artist’s Model Amp” before deciding on the name, the Fender Twin.
The 5D8 model, introduced in 1955, featured a modified preamp circuit and an improved power supply design.
Next came the 5E8 model, which featured a smaller cabinet. The speakers were now offset sightly to the lower right and top left corners instead of side by side. power jumped significantly thanks to new circuitry and the 5E8 now boasted 50 watts of power.
1955 to 1959, saw the model develop into the powerful E and F and G series. Fender were now unstoppable and these two models catapulted this amp to even higher levels of sophistication. The 6G8 model added a vibrato circuit, now up to 80 watts of power, and four 10-inch speakers, making it one of the most versatile and powerful amplifiers available at the time. It’s impact was immense.
In the 1960s, the Twin swapped its tweed covering for brown Tolex. This is the same time that its popularity skyrocketed in the 1960s, with musicians like Jimi Hendrix, Eric Clapton, and Stevie Ray Vaughan using the amplifier to create their own signature sounds.
In 1961 Fender decided on white Tolex and a maroon cloth grille cloth. Now the Twin sported an even more impressive set of controls including volume, treble and bass (normal channel) and volume, treble, bass, speed and intensity (vibrato channel). More colour changes very soon after when a wheat grille cloth arrived towards the end of 1962. These colour changes have certainly helped collectors easily identify the age of an amp. In the same manner, a black metal-reinforced handle replaced the brown handle in early 1963 -much needed considering the weight of the amp.
The “blonde” Twin amps of the early 1960s (models 6G8 and 6G8-A) were formidable amplifiers in their own right. No less than ten tubes and a tremelo to die for.
But still it didn’t stop.
In 1963 the amp you all want to find at the back of your dad’s lock up arrived, the reverb-equipped “Blackface” version. This model ran until 1967 and featured black Tolex.
Even by 1963 things were getting complicated with so many “Twins” being produced. Introduced in late summer 1963, the 85-watt black Twin Reverb featured a silver-sparkle grille cloth, a raised Fender logo and completely new dual-channel circuitry with bright switches for both channels instead of a presence control.
The “middle” tone control was back too, which had numbered and skirted black knobs and a black control panel (hence the term “blackface”). It is often called a “Fender Twin” or simply “Twin”, although it shouldn’t be confused with the tweed and blonde-era Twins, which had significantly different circuits and, of note, no reverb.
In 1965, CBS took control of the company, a significant milestone in the history of the Fender brand.
The mid-sixties would see the company experiment with solid state version of the Twin in an attempt to innovate and stay with the times. As we all know, it was an experiment that failed. (By 1969 no more solid state Twins would be produced and that would extend across the entire production line by 1971).
In late 1967 the Silverface Twin reverb, one of the first of the post-Leo Fender amps, would hit the shops. It featured a brushed aluminum control panel, aluminum trim, blue-sparkle grille cloth and a shallower cabinet. Its circuitry remained the same as its blackface predecessor for a short period until a bias balance control was introduced in mid-1968 (abandoned by late 1969). Power was boosted to a whopping 100 watts.
The Fender Twin set a new standard in guitar amplifiers
I know, it’s a much over-used phrase these days but the Fender Twin truly deserves the title of game-changer. it was its innovative features, constantly being updated and improved, that kept it miles ahead of the competition.
One of the standout innovations was its dual-speaker design. This allowed it to produce a more powerful and clear sound than any other amp on the market. Additionally, the amp’s tube-driven reverb and tremolo effects were also ground-breaking innovations. Whether you wanted to play clean, distorted, tor a combination of the two, which most guitarists did, the Fender Twin could handle it all with ease.
One of the key features that contributed to the Fender Twin’s signature sound was its all-tube circuit. Unlike solid-state circuits, which rely on transistors and diodes, tube circuits use vacuum tubes, or valves, to amplify the signal from the guitar. This results in a warmer, more natural sound that many guitarists prefer and still do to this day.
The Fender Twin’s tube circuit was also notable for its particular use of 12AX7 preamp tubes (called ECC83s in Europe) and 6L6 power tubes.
These tubes were chosen for their high gain and clean tone, which allowed the Fender Twin to produce a wide range of sounds but with great clarity. Over the years there have been endless predictions of the demise of the use of tubes in amplifiers. Yet here we are, decades later, and still the sound of a hot valve still cannot be improved upon.
The Fender Twin’s Influence around the world
Looking back at the sixties, although it was initially popular in the United States, it was in the United Kingdom where the Twins influence truly took hold.
One of the bands that certainly helped it to the forefront of music in the UK was The Shadows. Their use of the Fender Twin in their early recordings, particularly on their hit song “Apache,” helped establish the amplifier as a go-to for guitarists across the country. For a while, everyone wanted to sound like Hank who had played a key role with Fender in helping with the original brief.
As the Fender Twin evolved, so too did its impact on music.
Its distinctive sound and tone played a major role in the development of new music genres. Heavy metal and punk rock bands loved the Twin just as much as the Shadows did to create their unique sound.
That legacy also extends to the world of collecting and restoring vintage equipment. The amplifier remains a highly sought-after item, with collectors and enthusiasts striving to preserve and maintain these iconic pieces of musical history. Old Twins are now extremely collectible and demand ever higher valuations.
The Fender Twin: 1970’s and beyond.
Innovations continued into the 1970s and the one everyone remembers is the introduction of the master volume control on the Twin Reverb in 1972. This is something that is appearing on just about every amp now, but it’s taken a long time to become defacto. The Fender logo also lost its tail by 1976, and pull-boost and hum balance controls were also added.
Guitarists were still demanding more and more power and in 1977 power was upped to 135 watts in 1977. That said, this wasn’t Fender’s finest years and it was generally considered that quality had deteriorated around this time
The blackface became an option in 1980 and was the standard by 1982, which was the final year of production for the traditional Twin Reverb.
1982 to 86 saw the 105-watt Twin Reverb II. The famous 100-watt red-knob (later black-knob) version known as “The Twin” from 1987-94 were loaded with features but had little in common with the originals. The latter was a very popular model and is remembered as being the first Twin model to appear after CBS sold Fender in early 1985.
From the 1990s to today, we have seen a variety of superb reissue amps rediscover the genius of those early days and ensure that the Fender Twin remains as much of an icon today as it has ever been.
The Sound of Success
Can the Twin’s success be attributed to one particular attribute? I think not, but one feature that musicians always rave about is this amp’s ability over the decades to produce an incredibly clean sound at high volumes, making it perfect for live performances. Its dual speaker system and all-tube circuitry deliver a warm, rich tone that’s hard to match.
Another notable feature of the Fender Twin is its built-in reverb and vibrato effects. These effects give the amp an added layer of versatility, allowing musicians to add depth and texture to their sound without the need for additional pedals or effects.
“The Fender Twin is one of the most versatile amps out there. It’s been a part of my sound since my early days in music, and I continue to use it to this day.”– Eric Clapton
“The Fender Twin has been my amplifier of choice for decades. The clarity of its tone is unmatched, and it continues to inspire me to explore new musical territories.”– Jimi Hendrix
