Verified · 93/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AB763 Deluxe Reverb is the blackface Deluxe Reverb: a 1×12 combo with Normal and Vibrato channels, spring reverb and optical vibrato, and a pair of 6V6s on a GZ34 rectifier at about 22 watts. Its clear clean tone, early smooth breakup and deep reverb made it one of the most-used club and studio amps ever made.
