FENDER VIBRASONIC (BROWNFACE) Description

Introduced as the Model 5G13. This amp had a reversed control layout at first but went back to the original design shortly thereafter. In 1961, the grille turned to maroon, and in 1962, it turned to wheat. Later models used 2 X 12AX7 tubes in the tremolo circuit rather than the 7025 and 5881 tubes (Model 6G13-A). This amp was a very close relative to the Pro amp with vibrato and a 15 in. JBL speaker.
