Standel Custom Studio Bass - Normal preset

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

The Standel Custom and Studio Bass are all solid-state 1970 bass amps from Standel's El Monte, California era. Two channels, Normal (channel 1) and Bass (channel 2), each have a transistor input and gain stage with an Accent switch, a Gain switch on the Custom, and their own Volume, Bass and Treble. The channels sum into a two-transistor driver with a signal line out, feeding a transistor power amp on split ±40 V (Custom) or ±45 V (Studio) rails.
