BOSS MT-2 Metal Zone High-Gain Distortion Pedal

The BOSS MT-2 Metal Zone is a million-selling high-gain distortion pedal that has defined the sound of heavy music since its introduction in 1991. Celebrated worldwide as one of the most iconic drive pedals ever created, the MT-2 delivers the thick, saturated distortion tones and smooth, singing sustain that hard rock and metal guitarists demand. With over one million units sold, it remains the king of high-gain distortion stomps for guitarists around the globe.

At the heart of the MT-2 is an innovative dual-stage gain circuit that produces dense, heavy crunch and singing sustain at any volume. The first stage uses a mid-focused clarity circuit that feeds into an aggressive secondary gain stage, while seven cascaded filtering stages ensure the resulting tone stays tight and well-defined without mud or flub. The result is a distortion character that works beautifully across clean "pedal platform" amps as well as already-driven tube heads.

The MT-2's advanced three-band active EQ system—featuring a semi-parametric midrange control—goes far beyond the tone shaping capabilities of most analog drive pedals. Each band offers up to 15 dB of boost or cut, and the variable midrange frequency control sweeps from 200 Hz to 5 kHz, giving players precise control over their distortion character. Whether dialing in modern djent tones, classic thrash, or singing lead sounds, the MT-2 provides the tools to sculpt your ideal high-gain tone.
