This was an impulse buy for me but a very satisfying one. I have never gotten so many hours of cheap entertainment from one pedal. The 2 octave up mode lets me do over the top pantera guitar screams and the shallow detune effect on classic mode gives a very pleasant modulated chorusy effect (for doing songs like rooster by alice in chains it sounds quite similiar). The shallow detune effect is also great with distortion it reminds me of the song planets collide by crowbar and its quite psychadelic. Sometimes i switch it into the chord mode and put the whammy mode down a perfect 4th and i get instant djent satisfaction. You can also add a bass harmony or any kind of harmony really and create something totally unique. In conclusion I was hesitant about buying this pedal for a while but now that I have it I can say I will probably always have it on my pedalboard at gigs because it adds so much flavor to the sound as well as entertainment, enjoyment, and utility.
