I don't think I've ever read a single positive thing about the Boss MT-2 Metal Zone pedal online. Which is funny, because its predecessor, the HM2, is such a classic when it comes to getting Entombed-like tones. So maybe the key to making the MT-2 suck less is to string seven of them together?
Thomann International had that same thought, and the results are in! The MT-2 still sounds like shit. it doesn't matter if you have 1, or 7, or 56. You will also sound awful.
