Like most Boss pedals, the configuration of the Boss MT-2 Metal Zone is really easy to figure out. From left to right, it has parameters for level, two for EQ that each have two bands on them (high and low, and two middle frequencies) and then a knob of distortion. It is really easy to zoom in on whatever sound you might be after. The manual for the Boss MT-2 Metal Zone is pretty complete and thorough, but really isn't necessary when trying to learn this pedal.
The sound quality of the Boss MT-2 Metal Zone is respectable and like the name states, is best suited for playing metal or hard rock music. It is a really thick and heavy sounding distortion and because of this is pretty one dimensional. If you have an amp that doesn't have distortion like me, you probably have been looking for that perfect distortion pedal for a while now, but unless you play mostly heavy metal this probably isn't it. Don't get me wrong, the sound quality of the Boss MT-2 Metal Zone is clean and the distortion is big and heavy, but is really only suitable for one type of music. Being fair though, it doesn't really advertise to be anything more than that anyway.
I've been using the Boss MT-2 Metal Zone for about three years and while it is a good sounding pedal with a decent amount of parameters, I don't use it very often simply because I don't play the type of music that this pedal is intended for anymore. The price of this pedal makes it a very attractive option and I would encourage those interested in a distortion pedal in this price range to try out this pedal as well as some of the other pedals Boss and their competitors has to offer. All in all, the Boss MT-2 Metal Zone is definitely worth a try for those who play harder rock and need a thick sounding distortion pedal.
