Electro-Harmonix · pedal
The Electro-Harmonix Bass Big Muff Pi is a version of the classic Big Muff Pi fuzz circuit specifically voiced for bass guitar, with a blend control that preserves low-end definition while adding the dense, harmonically rich fuzz saturation of the Muff circuit. It features Sustain, Tone, and Volume controls alongside the essential clean blend, allowing bass players to add fuzz character without losing the fundamental low-end content that bass needs to function in a band mix. Suited to rock, metal, psych, and alternative bass contexts.
