PRELOVED Greenhouse Effects SludgeHammer — Doom / Stoner / Sludge Fuzz

The Greenhouse Effects SludgeHammer is a thick, textured doomy fuzz built to turn a clean amp into a riff machine—whether you’re running a solid-state combo or a big valve rig. Gain runs from medium crunch through to an “uncompromising wall of sound,” with the feel getting looser and fuzzier as you push it harder.

Tone shaping that actually matters

This pedal is all about shaping your amp, not copying one. The Tone control has an extreme range (from smoother to sharp bite), while Body focuses on low-mid frequencies and interacts with Tone—crank it for extra punch and heft.
