The AA763 Concert shared much of its circuit with the AA763 Super Reverb and Pro Reverb, delivering 40 watts of bright, articulate American clean tone through a 4×10 speaker configuration with onboard tremolo and reverb. The Concert is less famous than the Super Reverb but shares nearly identical tone.
