Electro-Harmonix by JHS Big Muff 2

Archaeology in the analog domain rarely yields such a consequential artifact. Unearthed from a trove of personal archives during research for the forthcoming Electro-Harmonix tome, the Big Muff 2 is not a revision but a resurrected parallel evolution—a spectral blueprint from the mind of original inventor Bob Myer, finally realized after five decades in stasis.

Discovered on a hand-drawn schematic, Myer’s concept proposed a radical re-articulation of his iconic fuzz using the then-novel dual op-amp, a technological leap from the original transistor-based circuit. This “lost” design predates and diverges from the famous late-’70s Op-Amp Big Muff, featuring a distinct clipping topology and an additional gain stage. Where the classic Muff sings with a violin-like legato, Myer’s op-amp iteration manifests with a more assertive, cutting demeanor. It delivers a pronounced midrange heft and seismic low-end authority, wrapped in a familiarly simple Volume, Sustain, and Tone interface.

This collaborative resurrection—spearheaded by JHS Pedals, Electro-Harmonix, and archivist Daniel Danger—is more than a new product; it is a speculative fiction made sonic reality. It channels the aggressive sustain and biting presence of Myer’s alternate vision, a road not taken that now runs directly to the modern pedalboard. It stands as a testament to the chaotic, brilliant history of EHX, a tangible echo from a workshop of ideas where even the founder, Mike Matthews, acknowledged this divergent path held “something special.” This is the sound of history’s shadow given voice.
