Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rebel was built in lead (L90) and bass (B90) versions that share a circuit and differ only in tone-stack values. Two inputs feed a 12AX7 stage, treble and bass controls and a second 12AX7 stage, with the volume on a rear-panel control. A 6AN8 provides the footswitchable Stinger fuzz with its own level, and a 6SN7 long-tail phase splitter drives a fixed-bias push-pull pair of 6V6GTs on a silicon rectifier.
