Mr Black Mr. Black SludgeMaster
Mr Black · pedal
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.
