The Sub Machine Fuzz combines shaggy fuzz with a growling sub octave circuit—switchable between series and parallel modes—with an octave up fuzz mode for searing subterannean sounds.

This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
