Originally sold as a companion to the Fender Musicmaster Bass Amp and the student-model Fender Musicmaster Bass, this amplifier has since become a favorite among guitarists.
 
With just two controls—volume and tone—it’s exceptionally straightforward to use and performs equally well on its own or paired with pedals. This particular unit is a 220V export version, meaning no external transformer is required.
 
The Fender Musicmaster Bass Amp is one of the hidden gems of Fender’s 1970s catalog. Though initially designed as part of a beginner bass package, it quickly gained recognition among guitar players for its warm, natural overdrive and rich midrange character.
Visually reminiscent of the Fender Champ Silverface, it offers several key differences. Most notably, it is equipped with a 12-inch speaker—larger than the Champ’s 8-inch speaker—resulting in deeper low-end response and a fuller, rounder tone. It also delivers 12 watts of tube power, roughly twice that of a Champ, making it well suited for studio work, rehearsals, and small live performances.
 
Production ran from 1970 to 1980 in a Silverface version, followed by a Blackface-style cosmetic update from 1980 to 1983. Early CFA7010 models featured a 6AQ5 tube circuit, later replaced with the more common 6V6 configuration.
