The ML-2 Metal Core is Boss's most aggressive distortion pedal, purpose-built for the crushing tones that modern metal demands. The gain on tap is massive, delivering tight, saturated distortion with a sharp attack that stays articulate even during fast palm-muted riffing. An integrated noise gate keeps things dead quiet between hits, which is impressive given how much gain this thing produces.

The two-knob EQ is simple but effective: Low control dials in the heavy low-frequency weight that drop-tuned and 7-string players crave, while High shapes the metallic edge and presence up top. From nu-metal to grindcore to industrial, the ML-2 delivers extreme distortion in a compact, road-tough Boss chassis. Runs on a 9V battery or optional adapter.
