Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender Deluxe Reverb AB763 is the quintessential American clean platform — a 22W 6V6-powered combo with vibrato and spring reverb that defined the blackface era. Its two channels share a tone stack producing Fender's signature warm low-mids, glassy highs, and a touch-sensitive breakup that rewards dynamic playing. One of the most recorded guitar amplifiers in history.
