Boss MT-2 Metal Zone

The Boss MT-2 Metal Zone is one of the most recognisable distortion pedals ever made — and one of the most argued about. Since its introduction in 1991, it has appeared on countless pedalboards, recording sessions, and rehearsal room floors, becoming the defining voice of high-gain crunch for a generation of metal players.

At the heart of the MT-2 is a dual-stage gain circuit that pushes hard into aggressive distortion territory, generating the thick, singing sustain and tight low-end attack that the Metal Zone is known for. What sets it apart from simpler fuzz or distortion pedals is the three-band active EQ section, which offers up to 15 dB of boost or cut per band. Critically, the midrange band has a sweepable frequency control spanning 200 Hz to 5 kHz — giving you the ability to scoop the classic mid-scooped metal tone or dial in a more cutting, presence-heavy sound. This level of tonal control in a compact stompbox was genuinely ahead of its time.

The MT-2 also has a significant aftermarket: it became a favourite of boutique pedal modifiers, with companies like Keeley Electronics and Analogman offering mod kits and modified versions that tighten the low end and smooth the high-frequency harshness some players find in the stock circuit. A modded MT-2 on the used market often trades at a premium, and is worth seeking out if you want the character without the brightness.

Three controls — Dist, Level, and the EQ section — keep operation straightforward. The buffered bypass means your signal stays strong in larger chains, though true-bypass purists occasionally take issue with this. Battery life is modest at around 12–23 hours depending on battery type, so a power supply is recommended for regular use.

Despite its reputation as a beginner's metal pedal, the MT-2 has appeared on records across metal, shoegaze, and experimental music — often used against its intended purpose for textural or ambient effect. Its polarising character is part of its appeal.

Who Is This For?

The MT-2 suits guitarists who want an affordable, high-gain distortion with serious EQ flexibility. It's a natural choice for metal, doom, and heavy rock players who need aggressive sustain and the ability to shape their tone. It also appeals to those interested in modification — a modded MT-2 remains one of the best-value boutique distortions available on the used market.
