The MT-2 is the metal pedal that followed the HM-2. It was released a couple of years before the HM-3 and was an instant success. It is one of the best selling Boss pedals of all time. The Metal Zone produces a distortion that is a bit smoother than the HM-2 and HM-3. In addition to the LEVEL and DIST controls it’s got a 3 band sweepable parametric equalizer that gives complete control over the MT-2’s tonal spectre.
