Overall, this is a fantastic utility pedal to have in your arsenal. I've used it in the studio to great effect, reamping kick drums and snares, as a DI for bass (obviously) and keyboards, even as a pre-EQ on dynamic mics once or twice. If you're creative, this pedal can do a lot of things!
On the downside, I found it annoying at times when I wanted to use the pedal as an "always on" preamp but couldn't set the amount of overdrive without affecting the mids. There's only so much room in teh box, I suppose but I would have preferred to have the drive be an entirely separate knob.
Overall, definitely an excellent piece of kit and one that I'm glad I have available whenever I need it.
