FAQs

What makes the Boss HM-2 Heavy Metal pedal unique for metal music?

The Boss HM-2 Heavy Metal pedal is renowned for its distinctive "chainsaw tone," which is a defining sound in Swedish death metal. With all knobs maxed, it produces a gritty, aggressive distortion that has become iconic in the metal genre.

Is the Boss HM-2 Heavy Metal suitable for genres other than metal?

While the Boss HM-2 is famous for its metal tones, it also offers versatility for other genres. By adjusting the settings, it can deliver milder distortion suitable for shoegaze and other styles that benefit from its unique character.

Can the Boss HM-2 Heavy Metal pedal be used as a fuzz pedal?

The Boss HM-2 is primarily a distortion pedal, but its tone can resemble fuzz when all controls are maxed out. This unique characteristic allows it to produce a thick, saturated sound that blurs the line between distortion and fuzz.

The Boss HM-2 Heavy Metal pedal was manufactured from 1983 to 1988 in Japan. It remains a sought-after piece of gear due to its historical significance and unique sound profile.

How does the Boss HM-2 Heavy Metal compare to other Boss distortion pedals?

Unlike other Boss distortion pedals, the HM-2 offers a distinctive "chainsaw" tone that is particularly suited for metal and aggressive music styles. Its sound is more raw and gritty compared to the smoother tones of other models like the Boss DS-1.

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Boss HM-2 Heavy Metal.

Setup and maintenance

  • Vintage HM-2 pedals perform optimally with 12V ACA power, but using a 9V regulated power supply may lead to voltage starvation and diminished sound.

    Source

Features and functionality

  • When powered correctly, the HM-2 achieves a "chainsaw" sound, which is lost when the pedal is voltage-starved in a pedal chain.

    Source
  • The HM-2w's Custom mode offers a different EQ curve and significantly more gain, even at zero gain settings, compared to the Standard mode.

    Source

Mods and upgrades

  • Daisy chaining ACA pedals with PSA pedals can bypass voltage reduction, allowing the HM-2 to function at full capacity without modding.

    Source
  • Behringer HM300 is recommended as a budget-friendly clone of the Boss HM-2 with additional controls.

    Source

User experience

  • Some users prefer the sound of a "starved" HM-2, finding it suits their tonal preferences even if it deviates from the intended design.

    Source
  • Owners appreciate the HM-2w for being more pedalboard-friendly due to its 9V power compatibility, unlike older models.

    Source
  • Some users prefer the Custom mode exclusively, finding it superior and more versatile than the Standard mode for their needs.

    Source
  • Users report that the MT-2 requires careful EQ adjustments to achieve desired tones, especially when used with a dirty amp.

    Source

Use cases and applications

  • Blending the HM-2w with a clean signal using a Boss LS-2 Line Selector Pedal provides a versatile range from subtle presence to intense distortion, especially for bass.

    Source
  • The HM-2 is favored for playing black metal due to its darker tone, while the MT-2 is considered too bright for the genre.

    Source

Comparisons

  • The HM-2w's tonal versatility challenges the perception that it only excels at the "Swedish chainsaw" sound; many users find a variety of tones suitable for different musical styles.

    Source
  • The HM-2's sound is more authentic to classic metal recordings, making it suitable for band settings with cranked amps.

    Source
  • The Empress Heavy Menace is suggested for those seeking a balance between the brighter MT-2 and the darker HM-2 sounds, with an included noise gate.

I don't think I have to say anything...

I mean, if you buy it, you KNOW what you're getting. That said, I'm not a fan of the whole "turn it all up to 11" shtick. This pedal offers so much more, and combined with a Noise Gate cross-wired, you can really taming to your personal liking. I usually have the Level and Distortion at 12 - depending on the setup - the bass on full and the high around 4. Crushing, yet not overpowering. Goes well with an already high-gain amp like the Marshall JCM900. Put a TS style pedal in the loop for more shape control.

Disgusting

Thank you Left Hand Path for bringing this pedal in to everyone's lives. The most disgusting chainsaw noise that is just so sweet to my ears

Legendary for a reason

Despite being known as the sound of black metal, this pedal is incredibly versatile. Its EQ section can make some pretty bizarre tones aside from the Swedish Buzzsaw. Personally I love it as sort of a heavy overdrive, with Low EQ at 3:00, the high at 11:00 and the distortion at about 10:00. With those settings it makes a tremendous distortion for softer shoegaze tones.

Everyone knows how great this pedal sounds. What you might not know is that this is hands down the toughest pedal ever built. I bought mine back in 199x, the first distortion pedal I ever owned. Sometime in the early 2000s it was in a flood in my apartment. Despite being submerged for about 24 hours, I let it dry out for a couple of days, and it never lost a step. It’s the one pedal I can’t see ever coming off my board, both because I don’t think it will ever die, and because there’s no style of music it can’t handle.

Simply the best distortion ever

Unreal power in a box, this pedal provides the best distortion I've ever heard it has bottom, raw mids and chainsaw type highs. It needs 12v however you can use it along the dc out that the TU-3 provides it will work perfectly...

Preferred Settings + Usage:

Everything on 10!! Chainsaw Swedish Death metal all the way

dusanslavysynjanek

cult no. 1!

cult pedal. waza is better but this is... simply cult! if you are death metal fan you must have it!

solusash

Swedish Buzzsaw

Dime everything. Get legendary tone.

But seriously, I use this for Doom/Stoner Metal, and believe it or not, don't actually crank everything to 11. You CAN do that, but if you tweak the colours, you get a really wild distortion that, when mixed with an Akai Phaser set to 270 degrees and a fast repeat, is ball-trippingly freaky.

Everyone should have one of these. Or the Berhinger clone, but it don't sound the exact same--you have been warned.

Boss HM-2W Heavy Metal Waza Craft

$146.87 - $164.99

newer similar sound mod

Official re-release: https://www.boss.info/global/products/hm-2w/

Produced from 1983 to 1991, the BOSS HM-2 Heavy Metal is a true legend in the history of distortion pedals. Its signature “chainsaw tone” with all knobs maxed is the defining voice of Swedish death metal, and the slightly milder sides of its personality can be heard on tracks from mainstream to shoegaze. After years of requests from hardcore HM-2 fans, the iconic stomp is now reborn three decades later in a special Waza Craft edition. The HM-2W delivers the authentic analog sound of the original in all its glory, coupled with lots of modern refinements for enhanced performance.
