FX55B Supra Distortion

The DOD FX55B Supra Distortion is a high-gain distortion pedal originally manufactured in the late 80s and early 90s. It features a three-knob control interface, providing a symmetrical standard distortion sound with a boost of gain in its upper range. The pedal operates on 9V power and offers buffered bypass functionality. The FX55B is an analog pedal that is designed to produce a high-gain preamplifier effect, overdriving the input signal to create sustained notes and characteristic distortion similar to an overdriven guitar amplifier.
