Acoustic 117 / 118 preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Acoustic 117 and 118 are late-1970s solid-state amplifiers from Acoustic Control Corp sharing one power board. The 117 lead preamp is a discrete-transistor design with Treble, Bass and Mid, Volume with Bright switch, spring reverb with level control and footswitch, and a Master Volume. The 118 bass preamp has 0 dB and -10 dB inputs, the same Treble/Bass/Mid stack and Volume with Bright switch, and no reverb or master.
