Fender Prosonic - Drive preset

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

The Prosonic is a mid-1990s Fender Custom Amp Shop design with relay-switched channels. Channel 1 has its own Volume; Channel 2 cascades extra 12AX7 stages with Gain 1, Gain 2 and a Master. Both share Treble, Bass and Mid, followed by a 12AT7-driven spring reverb, an effects loop and a 12AX7 long-tail phase inverter. A pair of 6L6GCs give up to 60 watts, with a rectifier switch choosing a GZ34 valve or silicon diodes and a power-stage bias mode switch.
