A strange one, indeed. BOSS was obviously looking to attract a niche crowd with this distortion pedal that incorporates two different circuits. Circuit one is pretty much a stock analog distortion while circuit two provides an additional five (FIVE!) different non-modes for doubling and chorus effects coming from newly discovered digital planets.
Doubling one: REALLY REALLY short delay for an almost slap back echo
Doubling two: REALLY Short delay for an almost slap back echo, the mode I use second most
because I really seems to be the sweet spot and hit what the developers were trying? Doubling Three: Short Delay for short slapback-esque sound Chorus one: Light Chorus (this was made in the eighties, right?) Chorus two: Light Flange. To my ears this just sounds too good to not use this one the most.
This pedal is ALOT of FUN to play! one is able to create all sorts of aquanet sounds from this monster and it's a BOSS, so it'll be around forever...and all of your friends will laugh at you once you tell them the name...Digital Metalizer, by BOSS?!?
Boss hidden gem; truly great pedal. Its name might be confusing and discouraging, so let me clear - this is a two-circuit pedal. Analog for distortion, digital for chorus and doubling feature. Starting with distortion: MZ-2 stands quite close to DS-2 since they were released in almost the same time. Heavy, saturated and lots of gain available. Fav settings so far: LEVEL: 3:00 TONE: 11:00 DIST: 2:00.
However the biggest fun starts with MODE Knob. SGL: "single" distortion, so you get ONLY distorted signal. DOUB I: here starts the doubling. In fact this mode does not give much difference, the signal is just a little bit fattier. You need to play 5 minutes in this mode, then switch back to single in order to feel the difference. DOUB II: Call me stupid, but quite close to Black Album tone (put a SD-1 in front MZ-2 to get even more). Fat, heavy, addictive. DOUB III: too much, sounds more like very loud digital slap back delay. Not very useful. CHO I: subtle chorus, CE-2 simulation with rate and depth on 10:00. CHO II: more audible chorus, CE-2 simulation with rate on 10:00, depth at 2:00.
Stereo is awesome and this is what makes MZ-2 shine. Absolutely love MZ-2, worth getting!
