Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The EarthQuaker Devices Gary is a fuzz pedal modeled on the Op-Amp Big Muff circuit made famous by 1970s Sovtek-era designs, voiced with particular attention to nasal midrange content and aggressive sustain. It captures the thick, complex fuzz character of the op-amp topology with added gain and tonal controls for modern flexibility. The Gary suits heavy lead playing, stoner rock, shoegaze, and any context requiring a wall of harmonically rich fuzz sustain with a distinctively edgy top end.
The Mr. Black SludgeMaster is a fuzz based on a classic 1970s IC-based fuzz circuit, delivering a super-heavy, harmonically full fuzz tone with a woolly character, punchy and articulate midrange, and thick op-amp grind, cleaned up to run quieter and sound sweeter than the vintage circuit that inspired it. Volume, Tone, and Sustain controls shape the saturation, readily fattening single coils and driving humbuckers into a dense wall-of-sound. Tuned specifically for sludge, doom, and low-tuned heavy playing, it's still surprisingly versatile beyond that core use case. It suits doom, sludge, and stoner players wanting a powerful, saturated, characterful fuzz with real midrange punch rather than a scooped, thin heavy-fuzz voicing.
