BOSS ML-2 Metal Core Distortion Pedal

The BOSS ML-2 Metal Core delivers extreme, ultra-heavy distortion purpose-built for the most aggressive metal styles. Engineered as the most potent and heavy distortion pedal ever created by BOSS, it produces sharp-edged attack and crushing low-end presence that define the metal genre.

Designed specifically for modern metal subgenres including Nu Metal, Grind Core, Industrial, and Hard Core, the ML-2 features dedicated LOW and HIGH EQ controls that give players surgical command over their tone. The LOW knob dials in thick, resonant low-frequency punch associated with 7-string guitars and drop-tuned rigs, while the HIGH knob sculpts sharp, screaming metallic edge that cuts through any mix.

Built in BOSS's legendary road-tough metal housing, the ML-2 is engineered to withstand the rigors of nightly touring and stage use. The buffered bypass ensures signal integrity is maintained at all times, and a dedicated CHECK indicator doubles as a battery level monitor. A five-year warranty backs the build quality.
