The Nano Big Muff Pi 2 is a compact analog fuzz effect that revives a previously unreleased dual op-amp fuzz circuit. It delivers thick sustain, heavy fuzz, and a rich tonal character that sits between vintage Big Muff sounds and more modern grit. It includes simple controls for Volume, Tone, and Sustain so you can shape output level, EQ, and the amount of distortion and sustain. True bypass switching preserves the clean signal when the pedal is off.
