Oh man, this is one of the coolest pedals I have ever had! lush phase shifting meets ferocious fuzz! This pedal can be used as a straight ahead phaser or, when in Jet mode, it produces swirling roaring fuzz-phase that is extremely satisfying. Check out the video of Larry Graham rocking this pedal out with his bass. Works equally well for guitar...an utterly unique offering that does something that cannot be achieved simply by placing a fuzz before a phaser in your pedal chain. These pedals are coveted for a reason, folks! https://www.youtube.com/watch?v=q2w0dbTy2v8
