First of all, it's rock-solid. I doubt it would break if I threw it out the window. It's a big pedal though, much larger than your average pedal...

As for it's sound, it has great variety-very use-able for driving amps in general. It has a warm tube-like overdrive when driven on clean sounds. Plus, it's dirt cheap! Don't miss out on the distortion either-far better than some cheap boss distortion/overdrive pedals that cost the same.

This unit actually emulates POWER TUBE overdrive well. Other units which claim to sound like power tube breakup sounds more like preamp gain, which isn't as responsive or rich as power tube overdrive. The Wasabi OD has a very nice crunch over the clean channel, and the boost is nice for boosting your tube amp's gain (sounds bad with solid state). Sadly, the overdrive which this pedal provides is slightly buzzy (like most overdrives). But, it's a transistor overdrive, and there has to be a little bit of buzz. Overall... This pedal is best into a clean amp, you'd be better off getting a tubescreamer for a boost. Excellent pedal, but by no means perfect.
