Fender Musical Instruments

Founded by Leo Fender in the late '40s in Southern Los Angeles, Fender Musical Instruments is one of the largest musical instrument manufacturers in the world.The first big series of amplifiers were built in 1948. These were known as tweed amps, because they were covered in the same kind of cloth used for luggage at the time. These amps varied in output from 3 watts to 75 watts. This period was one of innovation and changes; While Leo made a Tweed Princeton in 1948 for his Professional 8 string Lap Steel guitar [very short lived, as later he would focus on 6 string Student models] later the Princeton would become a push-pull class AB tube amp, in 1948 it was a single ended Class A amplifier similar to the Fender Champ, with the output transformer mounted to the speaker frame and bereft of any negative feedback. Also, in 1964, the Tweed Champ amp would be reissued in black tolexin small numbers along with the newer model with the slant front panel and controls; the stacked plywood boxes Leo used often went uninventoried. In late 1963, he found a couple hundred Tweed Champ chassis boxes in these bins. He had had them chromed and printed in 1958; being frugal, he built them in black tolex with a chrome and black Champ nameplate, as he had money tied up in them already.

Fender moved to Tolex coverings for the brownface amps in 1960, with the exception of the Champ which kept its tweed until 1964. Fender also began using Oxford, Utah and CTS speakers interchangeably with the Jensens; generally the speaker that could be supplied most economically would be used. Jensens and Oxfords remained the most common during this period. By 1963 Fender amplifiers had a black Tolex covering, silver grille cloth, and black forward-facing control panel. The tremolo was changed to a simpler circuit based on an optical coupler and requiring only one tube. The amps still spanned the spectrum from 4 watts to 85, but the difference in volume was larger, due to the improved, clean tone of the 85w Twin.

A brushed aluminum face plate with blue or red labels (depending the model) for the guitar and bass amplifiers became standard features, starting in 1968. These cosmetic changes were followed by a new "tailless" Fender amp decal and a sparkling orange grillcloth on certain amplifiers in the mid-1970s.

Marshall Amplification

The largest British manufacturer of musical instruments, Marshall Amplification was founded by Dr Jim Marshall OBE in the early 60s in Hanwell, London. Originally a drummer, and drum teacher Marshall felt that he could produce better amplifiers cheaper than the Fender designs available at the time and so produced his first design based on the Fender Bassman. Cospmetically very different, this was the JTM 45.

Since then the company has grown dramatically to be the largest amplifier specialist world-wide.
