Background and influence
Boss HM-2 was first issued in 1983. It was originally manufactured in Japan and then in Taiwan.[1] It was designed to emulate the mid-range response of the Marshall stacks.[2] According to Michael Astley-Brown of Guitar World, compared to the other distortion pedals, the pedal offered "radically versatile low and high ‘Color Mix’ EQ controls with 20 dB of boost/cut."[3] Despite achieving a moderate success in the glam metal scene, the pedal was discontinued in 1991; it was succeeded by Boss HM-3 Hyper Metal and Boss MT-2 Metal Zone, latter of which became a commercial success.[2] In the 1990s, the pedal attracted a cult following in the underground heavy metal scene due to its formative influence over the Swedish death metal sound.[4] Entombed's 1990 album, Left Hand Path, cemented its use in the scene; the pedal is often used with its settings set to maximum to achieve a "buzz saw" sound. It is often referred to as "Swedish Chainsaw" by its fanbase.[5]
Many Boss HM-2 has been collected by guitarist of Entombed and Dismember.
Since its discontinuance, Boss HM-2 became one of the demanded pedals of the Boss back catalogue.[3] Different manufacturers have produced custom pedal clones to emulate its sound.[1][2] Guitarist and record producer Kurt Ballou has been cited as an influence for the pedal's resurgence[6] and bands such as Nails and Rotten Sound have also appropriated the pedal's sound for different extreme metal styles.[7] In 2020, Boss Corporation president Yoshi Ikegami announced that the pedal would be reissued as a part of the Waza Craft pedal series under the name Boss HM-2w. For the reissue, the company also established a Facebook group to seek design feedback from the fanbase.[5][7]
