The ultimate metal tone? An evolution of the brand's excellent Wurm distortion with the addition of an ultra-fast VCA-based noise gate, ideal for HM-2-inspired chainsaw tones. Heavy. Supplier's Notes: Fusing together the powerful evolution of KMA's highly regarded Wurm Distortion with an intuitive, yet versatile and ultra-fast Noise Gate, Guardian of the Wurm is the perfect metal monster. From chugging hard-rock, droning doom metal and grinding Swedish death metal, the beast abides. But through its highly tweakable control set, the pedal can be tamed to provide impeccable clarity to your riffs, making this the definitive dirt pedal for metal, prog-rock, shoegaze, indie and beyond.
