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, while the slightly milder sides of its personality can be heard on tracks in genres ranging from mainstream to shoegaze. This pedal sounds amazing! A great addition to your pedal board for that vintage heavy metal sound. Designed to emulate Marshall stacks!
