The KMA Machines GUARDIAN of the WURM fuses the legendary WURM Distortion with a powerful, intuitive noise gate, creating the ultimate high-gain monster. From Swedish death-metal chainsaw tones to prog-rock grit, shoegaze walls of sound, and even doom metal drones, this pedal gives you crushing distortion with total control.

Based on the cult-classic Boss HM-2 MIJ, the WURM was already one of the most flexible HM-2 inspired distortions available. The GUARDIAN of the WURM takes things further with a built-in Blackmer® VCA-based noise gate, expanded EQ, multiple clipping options, and advanced routing features – making it the most versatile dirt pedal in KMA’s lineup.
