The Mach 5 M90 is a Garnet valve amp from Winnipeg. Two inputs feed a 12AX7 stage, treble and bass controls, a volume with a bright switch and a rear-panel volume control, and a second 12AX7 stage. A second 12AX7 runs the tremolo with depth and a switch, and a 6SN7 long-tail phase splitter drives a fixed-bias pair of 6V6GTs on a silicon-diode supply. The Mach 5 Reverb variant adds a 6CG7-driven spring reverb with 12AX7 recovery.
