Sludgehammer Fuzz

Sludgehammer is a fuzz capable of demolishing buildings. It delivers a massive wall of sound, extended sustain, a rich variety of tones, and an additional booster that not only boosts the signal but also adds even more weight, thick lows, and compression.

Knobs:

Input - Controls the input signal strength, adjusting the intensity of the fuzz.

Output - Regulates the output signal level.

Boost - Adjusts the power of the additional gain stage, activated by the Boost footswitch.

Tone - Adjusts the ballance of low and high frequencies.

Mids - Controls the level of mid frequencies.

Switches:

Clipping - Switches between additional clipping modes: “I” uses a single LED, adding subtle compression; “II” combines an LED with silicon diodes, compressing the signal more heavily for a sizzly, sharp fuzz sound; “O” bypasses this stage entirely, allowing for a full, dynamic signal with maximum headroom.

Cut FQ - Changes the mid-frequency range affected by the Mids knob.

Bypass - Footswitch that activates the fuzz.

Boost - Footswitch that engages the additional gain stage, adjusted by the Boost knob.

Pickup sim - An internal switch accessible by removing the back cover, which activates an input buffer and guitar pickup simulator, resolving the typical low-input impedance issue with this type of fuzz (commonly referred to as “tone sucking”).
