Fender Dual Professional - Channel A preset

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

The Dual Professional is a 100-watt, hand-wired 2×12 combo from Fender's Custom Amp Shop in the mid-1990s. Two footswitchable volume channels, each with its own Fat switch, share treble, bass and middle controls. A 6V6-driven tube reverb with Dwell, Mix and Tone sits ahead of the preamp, and bias-vary tremolo, an effects loop and four 6L6GCs on a solid-state rectifier give it huge clean headroom.
