Modify Your Electro-Harmonix Green Russian Big Muff Nano (Mod Service)
You supply your Electro-Harmonix green Russian Big Muff Nano (No pedal is included). We modify the circuit to add a mids knob - which really helps the pedal cut through a mix in a live band setting as well as a two way stock / bright toggle switch. We also upgrade the knobs (check out these cool mini-Russian replica knobs from SRC Effects!) and green LED too!
