Electro-Harmonix / JHS Big Muff 2 Dual Op-Amp Fuzz 2025 - Red

Where the original Big Muff delivers that iconic "sweet violin-like sustain," Bob's two dual Op-Amp approach pushes into more aggressive, cutting territory. It's the Big Muff DNA with a sharper edge, more volume, and the most pronounced low-end and midrange of any EHX Big Muff ever. It expresses Bob's vision of aggressive sustain and cutting presence, with the familiar Big Muff control layout you know and love.  It’s the sound of what almost was.

Mike Matthews himself, after hearing our prototype, admitted it had "something special" even though it strayed from the traditional Big Muff voicing he typically preferred. Sometimes the best creations are the ones that don't follow the rules.
