The R90 Rebel is a Garnet valve amp from Winnipeg in the Rebel series. Two inputs feed one half of a 12AX7, treble and bass controls and a rear-panel volume, then the other 12AX7 half. A 6AU6 phase-shift oscillator modulates the output bias for tremolo with speed, depth, an on/off switch and a footswitch, and a 6SN7 long-tail phase splitter drives a fixed-bias pair of 6V6GTs on a silicon-diode supply.
