Dunlop Way Huge Doom Hammer Fuzz, model WM45

Dunlop · pedal

The Way Huge Doom Hammer Fuzz, model WM45, is a mini-format fuzz pedal from Way Huge by Jim Dunlop, based on Jeorge Tripps modification of a 1978 op-amp Big Muff circuit originally modified for the band Oranger. The Doom Hammer design is characterized by taut low-end control and more mid-presence compared to standard op-amp Big Muff designs, producing a dense, buzzy fuzz with a nasty, brash quality suited to doom metal, punk, and heavy rock applications. Premier Guitar reviewed the pedal as punky and brash with a pronounced midrange one associates with op-amp Big Muffs.

What stands out

  • “Dense, buzzy fuzz with taut lows and more midrange presence than standard op-amp Big Muff designs, producing a nasty, brash character associated with doom, punk, and heavy rock”

    — from the community notes

  • “The nasty, buzzy character at high Fuzz settings is an intentional feature suited to doom, punk, and aggressive rock styles”

    — from the reviews

  • “The op-amp Big Muff character with refined tonal balance is consistently praised by players who want op-amp fuzz”

    — from the community notes

  • “Players who prefer a warmer, rounder Big Muff character or who need the classic mid-scoop sound specifically will find the Doom Hammer voicing too mid-present for their taste”

    — from the reviews

  • “The Output, Tone, and Fuzz three-knob layout is simple and fast to dial in across a wide range from low-gain crunch to dense wall of fuzz”

    — from the community notes

Trade-offs

  • “featuring taut low-end control and more mid-presence that makes the fuzz more usable in full-band mixes than standard scooped big muff alternatives”
