The EarthQuaker Devices Barrows Fuzz Attacker is a germanium-transistor fuzz pedal based on the classic Tone Bender MkII circuit, representing a modern 21st-century take on that foundational 1960s fuzz design. It delivers cutting mid-focused tones with brilliant top-end grind and low-end authority from vintage germanium transistors that are responsive to guitar volume attenuation. At lower gain settings the Barrows sings with amp-like distortion and superb touch sensitivity; at higher settings it builds to crushing, sustain-drenched fuzz. Associated with blues, classic rock, and psychedelic styles.
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.
