Boss MT-2 Guitar Effect

Boss MT-2 Metal Zone: The Iconic High-Gain Distortion Pedal

Introduced in 1991 and still in continuous production, the Boss MT-2 Metal Zone has sold over one million units worldwide, making it BOSS's second most popular drive pedal after the DS-1. Purpose-built for metal styles, heavy rhythms, and soaring solos, it remains versatile enough to suit clean "pedal platform" amps as well thanks to its smooth character and active EQ with semi-parametric midrange. A key to its enduring success is the ability to achieve dense, heavy crunch and singing sustain at any volume, providing an instantly inspiring experience for players at every skill level.

What Sets the Metal Zone Apart

Inside, the MT-2 uses a unique analog design with two gain stages in series. First, you get a mid-focused clarity that feeds into the second stage's more aggressive character. Seven total stages of carefully tuned pre- and post-distortion filtering keep the tone tight and well-defined at every setting with no mud or flub. With its semi-parametric midrange control, you can set the mid frequency anywhere from 200 Hz to 5 kHz for pinpoint tonal sculpting.
