What Each Control Does

Dist
Crunch
Chainsaw
Gain amount. At maximum with all other controls at max: the Swedish death metal chainsaw distortion. At lower settings: 1980s hair metal crunch.
Level
Silent
Loud
Output volume. The HM-2 can produce significantly more output than the bypassed signal.
Low
Thin
Heavy
Bass frequency boost. The death metal setting has Low at maximum — this contributes significantly to the chainsaw low-mid character.
High
Dark
Bright
Treble frequency boost. At maximum with Low at maximum: the scooped, extreme EQ of the death metal setting.
Color
Low-Mid
High-Mid
Selects between two different EQ boost frequency ranges for the Low and High controls.

Settings by Genre

Swedish Death Metal
Dist10
Level5
Low10
High10

All controls at maximum — this is the specific setting used by Entombed, Dismember, and Carnage on the defining Swedish death metal recordings. The HM-2 into a clean amp at this setting produces the "chainsaw" character that cannot be replicated by any other pedal or amplifier combination. Into a Marshall or HH amp (as originally used) for the exact Stockholm sound.

D-Beat / Hardcore
Dist8
Level5
Low9
High8

Near-maximum settings for D-beat hardcore character. Slightly less than the full death metal setting allows a bit more note definition while retaining the extreme low-mid emphasis.

80s Hair Metal
Dist6
Level5
Low5
High7

The HM-2 in its intended original application — moderate Dist and EQ settings for 1980s heavy metal crunch. At these settings the pedal sounds like an aggressive but controllable distortion, very different from the all-max chainsaw character.

Punk
Dist7
Level6
Low6
High6

High Dist with moderate EQ — the HM-2 as a punk distortion rather than a death metal device. Into a cranked Fender or Vox at these settings it produces an aggressive, raw character suitable for fast punk playing.

Level5
Low10
High10

The death metal all-max setting used by L.G. Petrov and Uffe Cederlund on Left Hand Path (1990). This specific pedal with these specific settings into a Marshall or HH amp created the Stockholm death metal sound. The HM-2 has no clean signal component at this setting — it is 100% processed extreme distortion.

Dist7
Level5
Low6
High8

The HM-2's intended 1980s application — aggressive hair metal crunch. At these settings it is a usable high-gain distortion for the style it was designed for: Judas Priest, Accept, early Metallica-influenced metal.

Dist9
Level5
Low8
High7

Corgan has used the HM-2 as a studio tool for extreme guitar texture. Near-maximum settings but with slightly less extreme High, avoiding the brightest chainsaw character for a heavier but less nasal sound. Into a Big Muff-style amp setup for additional saturation.

Tips & Common Mistakes

  • The "all knobs at maximum" setting is not just a setting — it is THE sound the pedal is famous for. This specific combination of Dist, Low, and High at maximum creates a unique circuit clipping that isn't replicated at any other position.
  • The HM-2 was discontinued in 1991. Original units sell for £200–400. The Waza Craft HM-2W is a reissue that accurately reproduces the original circuit.
  • Into a clean amp (the Entombed approach): the full "chainsaw" character. Into a driven amp: the HM-2 produces a different, less extreme character as the amp's own gain stage colours the already-distorted signal.
  • The Color switch changes which frequencies the Low and High controls boost — in standard position they produce the death metal character; in the alternate position the character is different.
  • A noise gate is essential for recording at all-max settings — the HM-2 at maximum produces significant white noise floor between notes.
