A gruesome single knob adaptation of the dimed HM-2 chainsaw circuit, we’ve taken the classic death metal tone and tailored it to modern doom, sludge, and drone metal.

Thundering lows, punishing mids, and that unmistakable chainsaw grind, the Doomsaw is a visceral device designed specifically for downtuned guitar and bass.

Designed in collaboration with Nick Williams of Dunwich Amplification.

All pedal orders ship via Fedex 2Day or Fedex International Priority and typically arrive within 1-3 business days.

The traditional HM-2 Level, Low EQ, and High EQ settings are maxed internally, with the single Grief knob controlling Distortion.

An increased and extended Low EQ combines with a modified High EQ for a pummeling chainsaw dirge with reduced high frequency harshness.


Grief: Distortion.

Set the Grief knob towards zero and run the Doomsaw gyrating EQ into a high gain amplifier or your favorite fuzz / distortion pedals.

Set the Grief knob towards max and run it as your primary distortion pedal for unrivaled dimed Doomsaw fury.

  1. HM2 Cult

    If you want heavy this is your pedal. Well-built, straightforward, and punishing. Not a typical “Boss” recreation as the low end is expanded. However, with the expanded low end the mids sit exactly where you would expect with an HM2 style pedal. Aside from doom I would highly suggest this pedal for anyone searching for a crushing dbeat/crust tone.

  2. Ryan Vickers

    The quality is everything you’ve come to expect from anything Nick Williams; so top notch. I’ve been hunting for a perfect fuzz tone for years, not knowing exactly what I needed, and low and behold here it is. Tonally it’s somewhere between a Hyper Fuzz and a Big Muff. Can’t say enough good things about this dream fuzz!

  3. Zach J

    Has that classic HM2 tone with its own twist . It’s a great option if you want that HM2 tone. Another solid release from DID.

  4. Michael. Allegedly…

    The Doomsaw is pure sonic carnage contained and ready to release its tonal savagery with just a single knob. Even if you aren’t after the iconic “Chainsaw” tone. This pedal is as brutal as it gets tonality wise. Definitely a must have if you’re into Drop tunings and playing doomy riffs that sound like they’re clawing their way up from the pits of hell.

  5. Ilias

    Other reviewers describe it perfectly. I give it 5 stars. It’s diabolically-rounded and the balance on all tonal qualities is perfect. It’s totally crushing. Doom Saw is the perfect name for it.

    An awesome take on the classic HM-2 sound and different enough to stand out on its own. Crushing tone with a wide range of adjustable distortion, this pedal bulldozes everything in its path.

    Got mine today, it’s just outstanding. Taming the high end how they did really makes it for me, with my HM2, Wurm and Left Hand Wrath the chainsaw sound is uncontrollably wild as one might expect. But with this thing, I can run a boost into it to tighten it up and get a perfect At the Gates/Bloodbath sort of sound that isn’t really possible with my other HM2 inspired pedals. This is a must have for anyone wanting that “blended” HM2 sound that still has defined pick attack and chugs a little.

  8. Noah Whistler

    Do you wanna make tones that make the earth shake, then this is your pedal. I got my DOOMSAW in last week and it has not been turned off yet. It is super easy to dial in for your desired tone. One knobs keep it simple and effective. From a recording aspect it’s a breeze to track with. It’s an all around must have for anyone writing or playing heavy songs.

  9. Troy Fazzio

    Does it Doom has nailed it once again,
    With another great one knob pedal,
    With the Doomsaw!
    Killer pedal, thick and heavy,
    Great voicing on this pedal.
    Thank you Steve!

    The Doomsaw is the HM2 I didn’t know I needed. As others have said what really makes the DS stand out is it’s ability to maintain the lows which gives it a super burly push while giving you all the chainsaw nastiness you can handle on top. I’ve tried blending it with my fuzz pedals to make some incredibly heavy sounds and push my amp into “sounds like it’s about to die” territory. I’ve been using it a ton on bass as well where I think it really shines. I’m eager to throw it in a mix to hear how it cuts through. If you like doom and are chainsaw curious look no further.

    Amazing pedal. I never quite liked the boss hm-2, too nazaly for my sound. But this modded version is amazing. The added lows really make it a necessary pedal for anyone trying to play some kind of doom or blackgaze. Love it, and thanks for making it!

    this was the sound ive been chasing for my bass. takes me back to my highschool years

  13. Manny

    I received the Doomsaw as a birthday gift. This pedal does everything I wanted in a distortion. It really inspires me to play the meanest, slowest, most evil riffs. This thing is a musical chainsaw. I love it.

  14. Blake – Aiwass

    The quality and sonic devastation of this pedal are without parallel. Essentially, what you’re getting here is an HM-2 without the downside of an HM-2: the lack of clear bass. The brutality is off the charts yet notes are still clear. I can’t recommend this pedal enough.

    This HM-2 modded beast of a pedal is now my favorite addition to my collection. Sometimes less is more, so having the one knob allows you to adjust the level of snarl that you need for your guitar or bass. I also like that it keeps you from making poor EQ decisions – especially because the tone on this is absolutely perfect. So no more nasally HM-2 user errors!

    Add this to a fuzz pedal, Wah or MXR Phase 90 pedal during recording and you’ll be very pleased with this pedals versatility. If you’re thinking about buying it…just do it.

    It dooms.
