Polyphonic Octave Mode can be used to play chords and it sounds awesome. You can dial in this pedal so many different ways it's unbelievable. I don't know what the other's problems with use are, I thought this pedal was very easy to DIAL IN and get many sounds but I guess if you don't have a GOOD EAR then maybe you will have issues. So whether your looking to make your own distinct sound (EVH, Navarro, Slash, Morello, etc.) or simply add some PHAT-FUNK sound this is your pedal. Very Versatile and Capable of a Wide Variety of Sounds. I don't want to forget to give TWO THUMBS UP to SAM ASH for FAST & SAFE Shipping and as always the BEST DEALS ONLINE!!!
