First, I love this pedal. As a keyboardist, organist & guitarist, from the moment I plugged this in and from the first notes, I fell in love with the sonic possibilities of the multi-octave generators right from the start. After all, that's how the organ can grow to such a monstrous cacophony of tones: simply by stacking octaves. But this pedal goes further by allowing you to set the level for each particular octave. Amazing concept. The attack delay, LPF & detune, and their button controls, also round this pedal out as a fantastic tone shaping tool. Simply put, it is an amazing sounding pedal. Polyphonic tracking is dead on, sans audio glitches (except for that with my noise gate, below). The eight preset slots at first don't seem like enough memory for all the different settings this pedal can handle, but the more I use it, the more that eight become more than enough. Very intuitive. The only sonic downside I noticed was when I had this pedal installed after my preamp and Silencer noise gate, the gate seems to mess with the polyphonic tracking of the POG; this was quickly remedied by placing the POG first in the signal chain before the gate. This is a bit on the pricy side for an EHX pedal, but if you have the cash, it is well worth the money for everything it can do. You will love how it makes your guitar sound.
