The Fender Bandmaster Reverb AA768 added onboard spring reverb to the Bandmaster piggyback platform, arriving with the early silverface cosmetics of 1968. Two channels, vibrato, and tank reverb gave players a complete feature set in a head/cab configuration. The AA768 circuit is a close relative of other silverface Fenders of the period, delivering that characteristic clean headroom with reverb and tremolo effects that helped define the American studio and stage sound of the late 1960s and early 1970s.
