A killer example of the highly sought after JHS Electro-Harmonix Green Russian Big Muff Fuzz Moscow Mod. Want more Muff from your Muff? That's where this one steps in.

The JHS Pedals Green Russian Pi "Moscow Mod" takes the classic Big Muff Green Russian pedal by Electro Harmonix and takes it to a whole different level with new modifications. Prepare to hear new levels of fuzz and overdrive with a much greater degree of control. A new Mode switch allows for lower/higher gain sounds, or bypasses the mods altogether leaving you with the original EHX Green Russian fuzz tone. A Geiger switch controls the amount of feedback within the pedal, allowing you to push your tone to the very limits. The Moscow Mod Green Russian Pi includes everything you'll need to create a 'radioactive' tone and hone your fuzz exactly the way you like it.
