HM-2

Introduced in 1983, the legendary HM-2 delivers raw, aggressive distortion with a uniquely voiced midrange and powerful low end. Every setting brings a bold attitude and distinctive edge to any instrument. With all knobs maxed, it pummels an amplifier’s input to produce the signature “chainsaw” tone that defines the Swedish death metal guitar sound.
