Leo Fender began building guitar amps before he started manufacturing guitars.
Other notable accomplishments of this period include the shift of the top-of-the-line model from the traditional Twin-Amp to include other models, like the Vibrasonic Amp in early 1960, as well as the blonde Showman Amp in 1961.
Beginning in mid to late 1961, Fender introduced another color combination: a smoother but still light brown tolex with a dark maroon or "oxblood" grillcloth.
By mid-1961, after this short-lived look, Fender was using the darker brown tolex which was a mainstay for many of the mid-1961 to 1963 amps.
The finishes were baked in the Kauffman family oven.
They were made in three different sizes, 1×8" (one 8" speaker), 1×10", and 1×15".
