Arriving at the end of 1987, the MZ-2 Digital Metalizer pedal was aimed squarely at heavy metal and hard rock musicians. Notably, Boss used the word musicians as opposed to guitarists, indicating that they saw it being employed on other instruments too.
Although the MZ-2 was called the Digital Metalizer, it wasnt all digital. The distortion was produced with analogue circuitry, and only the complementary effects were driven by ones and zeros. Of course, in later times, the pedal would, Im sure, have been named the Analogue Metalizer, but this was 1987 digital was still very much the buzzword.
The MZ-2 took a highly-saturated and heavily-processed distortion sound, of the type which would require multiple gain stages and maybe some custom EQ options to produce in a valve amp, and amalgamated it with additional digital delay/modualtion processing, in stereo, for an archetypal late 80s metal sound with spatial characteristics.
En excellent état.
