Unleash waves of frothy, shaggy fuzz tone with the MXR SubMachine guitar effects pedal. It's the perfect combination of the La Machine Fuzz with MXR's tried-and-true sub octave circuit - just what you need for absurdly heavy tone. Dial in the ideal fuzz and even kick in an octave up when the mood strikes you via a dedicated footswitch. The actual Octave control puts the sub in SubMachine, allowing you to roll on as much sub-octave thickness as you like. What's more, the SubMachine includes a Series switch, which lets you run the sub octave either through the fuzz effect or keep it clean by running it parallel.
