The G45TR Revolution I is a Garnet combo from Winnipeg with reverb and tremolo, shown here in its late version (the preamp sheet is shared with the G90TR). Two inputs feed a 12AX7 stage with a mids control, then treble, bass and volume with a bright switch. A 12AU7 drives the spring reverb with a footswitch, a 12AX7 phase-shift tremolo has speed and depth, and a 12AU7 mixer with master volume and split-load inverter drives two fixed-bias 6V6GTs on a silicon supply.
