Fender Super Reverb AB763 - Normal preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The blackface Super Reverb is a 4×10 combo with Normal and Vibrato channels, each with two inputs, volume, treble, bass and a bright switch; the Vibrato channel adds a middle control, spring reverb and optical vibrato with speed and intensity. A 12AT7 inverter drives a fixed-bias pair of 6L6GCs from a GZ34 rectifier into a 2-ohm load. The four 10-inch speakers give it a full, bouncy clean tone and a rich breakup when turned up, making it a longtime blues favorite.
