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.34% — somewhat different

The Keeley Moon Op Amp Fuzz is a high-gain op-amp Big Muff-style fuzz, extracted from the quad-op-amp Muff circuit inside Keeley's Gilmour-inspired Dark Side workstation and beefed up as a standalone pedal. It is thick, massively saturated and bass-heavy, with a wealth of harmonic content and a wall-of-sound sustain that makes thinner fuzzes sound weedy alongside it. Volume, Filter and Fuzz controls are joined by a three-way voicing switch offering classic scooped mids, a flat EQ, and a Full setting with pronounced midrange for cutting through a band. The Filter control has a notably wide usable range, running from dark and woolly to sharp and cutting. Suits players after heavy, doom-leaning and Gilmour-style op-amp Muff tones.
The ProCo RAT 2 is a classic hard-clipping distortion pedal whose circuit dates to the late 1970s, built around an LM308 op-amp and silicon diode clipping. Its three controls are Distortion, Filter, and Volume, with the distinctive Filter knob acting as a reversed tone control that runs from bright and cutting to dark and warm. Capable of far more than its name suggests, it spans gritty low-gain overdrive, thick midrange distortion, and nearly fuzz-like saturation while keeping notes present and clear even at high gain. It is a staple of punk, grunge, garage, stoner, doom, and alternative rock, and has been used by players from Jeff Beck and Thom Yorke to countless heavy and experimental guitarists. Dynamic and harmonically rich, it cleans up with guitar volume and stays articulate rather than overly compressed.
