There were only six amplifiers covered in tolex originally, the Professional Series: Bandmaster, Concert, Pro, Super, Twin (production halted Feb-May 1960, resumed as the blonde Twin) and Vibrasonic.These were considered a step above the student models (Champ, Harvard, Princeton) which remained tweed-covered in 1960.Other changes include the shift of the top-of-the-line model from the traditional Twin to include other models, like the Vibrasonic in early 1960, as well as the blonde Showman in 1961.Fender began using silicon rectifiers to reduce heat and voltage sag caused by tube rectifiers, and introduced an all-new, very complex vibrato circuit. The circuit was also changed to include a tremolo effect, and the output was increased.The name 'brownface' stems from the brown-colored control panels, common to both the brown- and cream/blonde- Tolex-covered amps.

The twill covering was first used in 1946 on the Dual Professional, a twin 10" 6L6-powered model of which only 400 were made before being renamed "the Super Amp" in 1948.Grillcloth was initially the same as used in the previous tweed era, maroon with gold stripe.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.Between 19, there were three different grillcloth colors: wheat, brown, and maroon and many tolex-grille color combinations are found suggesting that Fender was not reluctant to use up whatever stocks of materials were on hand.
