Well, the pedal is excellent, functioning as both an Overdrive and Distortion, allowing for some very good sounds, both for slightly overdriven rock and heavy or thrash metal. Its metal construction means that there won't be any issues there. The only negative thing I would say is that when the battery runs out, it distorts the sound a lot, and it consumes the battery very quickly (at least for me, as I play quite a bit). But if you have a problem with that, you can get a power supply (just be careful to get one from Boss) and you're sorted
