EHX has released a classic Big Muff in the Green Russian, and JHS want to take it a step further. They’ve created a radioactive mod that turns this classic fuzz/overdrive into a mutant tone machine. On the left side of the pedal they’ve added two toggles, the lower toggle is the Mode toggle, and the upper toggle is the RADS toggle. The Mode toggle has three positions: down is Mode 1, middle is off or stock mode, and up is Mode 2. When in the stock position none of the other modifications will affect the sound. When in Mode 1 you will have a lower gain synth style gated fuzz sound. Experiment with all the knobs to see what kind of sounds you can get. When in Mode 2, you have a high gain synth fuzz sound that will give you crazy oscillation sounds that are affected by putting all the knobs at different settings. The RADS toggle acts as a +/- toggle to give you less radiation… or more!

The Geiger knob on the ride side of the pedal acts as a gain control for the feedback within the pedal. Turned all the way clockwise the feedback is fully enabled. All the way counter-clockwise is fully stock

This mod goes from 60s vintage fuzz all the way to face melting modern sludge!
