this thing is awesome… sounds just like my FZ-2 did. other than the super el cheapo plastic housing, it seems to be well built with dampened pots and solid switch, which are plastic as well. the pedal is quiet by itself but noisy stacked. this is truly 3 pedals in one. Fuzz 1 of course is a mega-middy Super Fuzz close, but based on the BOSS clone which is not so fuzz-like (think less fizz and more boom)… perfect for Sabbath and doom. Fuzz 2 clones the Shin-Ei FY-2, which is also accurate: scooped, compressed and very dirty… perfect for The Jesus & Mary Chain and other noise rock. Boost is great. i can't tell if it actually colors my tone but it works as well as my EP Booster did: pushed overdrive sounds really good. Perfect for "Rumble" by Link Wray and other classic rock.
