An excellent overdrive pedal, brilliant for blues and classic rock. I play an ash-body Strat through a Marshall MG15 amp, and it sounds beautiful. With the gain knob on full, you get a really nice rock 'n' roll tone perfect for the kind of chunky rhythm that I usually play. It's also great for the limited lead work I can play, can't say for anything too complex or fast. Turn the knob down and you can get a really subtle distortion that works great for just about anything where you don't need heavy distortion.
Oddly, my Ibanez AEL40 electro-acoustic also sounds great through this pedal, it sounds almost like a fuzz pedal. If you try this though, make sure you're sitting across the room and pointed away from your amp, feedback is a big issue.
I don't expect any hard rock or metal players to be looking at this page, but i would just say this pedal is not a metal pedal; you would be much better off with something like the ML-2 (which i also have)
Thanks, i hope this review was helpful
