I really love this pedal. It's my favorite at the moment. Daft as it sounds, I play mainly acoustic Irish tune sets, and for the odd solo I turn this on. It lives on my pedal board next to the Boss E.Q. pedal, and my wireless (AKG) receiver. If like me you use an Acoustic guitar then watch the input level or you may get feedback. That's a bit of a faf, but to see peoples faces when I turn it on and distort the sound is worth the setting up. I've stopped using my bad monkey altogether now, (and the zoom G1, which had too many effects on it to use and adjust on stage) and took it off the pedal board. Keep it simple, and this does it well.
I have to say that for the money I got it it is really good pedal. Both from sound and quality point of view. It is in strong box. You do not have to fear to step on it. Sound is also quite fat and cruncy which I like very much
I do not have any bad word for it. If you are on a budget go for it.
