Fender Super Twin preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Super Twin is a CBS-era Fender amp rated at 180 watts RMS from six 6L6GCs run as three push-pull pairs. Its single channel has volume, treble, bass and middle with a bright switch, then a diode-clipped distortion circuit with its own level and a footswitch, an output level control, presence, and a five-band LC equalizer (100 Hz to 2.3 kHz) that can also be footswitched. A 12AX7 long-tail inverter drives the output valves through 12AT7 driver stages.
