Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.47% — somewhat different

The Electro-Harmonix Op-Amp Big Muff is the late-1970s IC-based version of the Big Muff, famous as the crushing, scooped wall-of-fuzz on Smashing Pumpkins' Siamese Dream. Unlike transistor Muffs it has a more aggressive, mid-scooped, slightly gated voice with massive sustain. It suits alternative rock, grunge and shoegaze players seeking thick, saturated, layered fuzz.
The Electro-Harmonix Ram's Head Big Muff reissues the early-1970s Ram's Head Muff, known for a creamy, articulate fuzz with exceptional sustain, rich harmonics, and a distinct mid scoop suited to soaring leads and thick wall-of-sound rhythm. It is growlier in the midrange than Russian-style and triangle Muffs, with smoother, more sonorous sustained notes, splitting the difference between a triangle's silicon fizz and a Russian Muff's smooth contours. It has less low end than many Big Muffs, making it tighter, more controlled, and more articulate, with the mid scoop present but balanced enough to preserve string definition. Famous for screaming leads and long, violin-like sustained bends in the David Gilmour vein, it sits between classic fuzz and distortion. With Volume, Tone, and Sustain it suits psychedelic, classic rock, shoegaze, and lead-focused players.
