1983 Boss HM-2 Heavy Metal Pedal Black Label Made in Japan

1983 Boss HM‑2 Heavy Metal – Black & Orange

The Altitude Summary

Dial in the “buzzsaw” tone that defined an entire genre with this 1983 Made-in-Japan Boss HM‑2 Heavy Metal—likely from March 1983 (serial 340068 inside). It’s in very good condition, with minor scuffs and dings that add character but don’t compromise function. This pedal rocks hard, with all knobs, switch, and jacks fully operational. Housed in the iconic orange chassis and weighing just over 14 oz (≈400 g), it’s pedalboard-friendly and built to withstand years of low-end annihilation.

Cult-Toned Destruction with Roots

This is more than a distortion box—it’s a cultural artifact. Designed to emulate Marshall stacks, the HM‑2 went on to define the buzzsaw mid-scooped tone that powered Swedish death metal in the late ’80s and early ’90s. From Entombed’s "Left Hand Path" to Dismember and beyond, this pedal is steeped in underground legend.Jukebox of Raw Aggression

With four controls—Level, Color Mix Low, Color Mix High, and Distortion—you can sculpt razor-tooth tones or uncork full-throttle annihilation. Every twist brings that iconic razor buzz or a refined guttural chug, all without over-complication.

Built for Battle, Not for Looks

This early MIJ HM‑2 is as reliable as it was when new. The footswitch clicks with authority, the pots have aged gracefully, and the case still stands firm under pedalboard pressure. It’s a survivor.
