This pedal works ok for practicing. If you have an amp with no distortion whats so ever, I guess this will get the job done. But I STRONGLY advise against recording using this pedal. Have tried to run it to an amp and mic it. Have also tried running it straight in to a recording device, and the result is always the same: a god-awful, horrible-sounding muddy tone that cannot be helped with all the EQ in the world. It is not good for metal, or any other genre for that matter. I realize it is probably not meant to record with, but i feel that anybody who is searching for a good studio guitar tone should certainly look elsewhere. If you have a combo amp, the distortion on it is probably way better than you will get with this pedal. BOSS makes some great products, but this is definitely not one of them.
