The Boss HM-2 Heavy Metal is a distortion pedal known for a scooped, sizzling, buzzsaw-like saturation that, with all four knobs maxed, became the defining chainsaw tone of Swedish death metal. Entombed's 1990 debut Left Hand Path popularized this dimed HM-2 sound, and producer Tomas Skogsberg championed it at Sunlight Studios in Stockholm, where it also shaped the guitar tone of Dismember, Carnage, and Grotesque. At more moderate settings it can deliver milder, more usable distortion for mainstream rock and even shoegaze, but its real character and cult reputation come from the aggressive, harmonically dense, buzzing wall of gain at full saturation. It suits death metal and extreme metal players chasing that specific, instantly recognizable Sunlight Studios buzzsaw sound.
The Boss OS-2 OverDrive/Distortion combines two distinct circuits, a smooth, warm overdrive voice and a more aggressive, higher-gain distortion voice, with a Color control that blends between the two rather than forcing a hard switch. At the overdrive end it stays close to a natural, amp-like breakup; pushed toward distortion, it gets thicker and more saturated for harder rock and metal rhythm tones. This lets players dial in anything from a light, transparent boost to a heavily saturated crunch from one pedal. It suits players wanting the flexibility of two different drive characters, and the ability to blend between them, without switching pedals.
