This pedal comes with an interface that allows you to easily change your sound with your computer. It gives a great range of sounds from the fuzzy octave to a crunchy distortion back to a warm clean. The expression pedal is reliable, but has since broken, the only fault is a cut out of sound when you switch presets
I bought this pedal when I was only in my first years of playing guitar. I progressively learned how to build different effects on this pedal. There are many different settings to choose from. There is also a 20-second looper in the pedal. The looping function is actually where I learned to loop and make it sound half decent. I sprouted out from there and bought a Boss RC-300 and now am working with my own custom loop pedal. However, I have to give some credit to this little guy. It got me started.
