Boss MT-2 Metal Zone

The Boss MT-2 Metal Zone, introduced in 1991, is one of the most iconic and divisive distortion pedals in music history. Designed to cater to the burgeoning death metal and heavy metal scenes, the MT-2 features a dual-stage gain circuit and a three-band active EQ with a semi-parametric midrange, allowing for extreme tonal shaping. Known for its thick, saturated distortion and tight low-end, the pedal quickly became a favorite among metal guitarists while also generating polarizing opinions due to its aggressive tone. Despite this, the Metal Zone has sold over one million units, making it Boss's second-best-selling pedal after the DS-1. Its enduring popularity lies in its versatility and ability to produce massive distortion tones at any volume.

Historical Development

• Release (1991): The MT-2 was introduced as a successor to the HM-2 Heavy Metal pedal, offering more tonal control and higher gain levels. It was designed with seven filters for pre- and post-distortion shaping.
• Features: The semi-parametric midrange knob allows players to select frequencies between 200 Hz and 5 kHz for precise tone sculpting, while the dual-stage gain circuit ensures clarity even at high distortion levels.
• Legacy: The MT-2 remains in production today and celebrated its 30th anniversary in 2021 with a limited-edition MT-2-3A model.

Notable Players

• Kurt Ballou (Converge): Uses the MT-2 as a dirty boost by flattening the EQ and driving a tube amp into saturation.
• Simon Neil (Biffy Clyro): Incorporates multiple MT-2s into his rig for layered distortion tones.
• Ola Englund: Demonstrates its versatility by using it as both a preamp and a standalone distortion pedal for modern metal tones.
