Fender Tone-Master - Channel B preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Tone-Master is a 100-watt Fender head of the early 1990s with two relay-switched channels. Channel A is the cleaner side with volume, treble, bass, mid and a Fat switch; Channel B adds an extra 12AX7 gain stage with its own gain, treble, bass, mid, Fat switch and volume. Each channel has its own transformer-coupled effects loop. A 12AX7 long-tail inverter drives four 6L6GCs with adjustable bias and a selectable output impedance. There is no reverb.
