I got my Electro-Harmonix Polyphonic Octave Generator last night. This thing is just a trip! I can't get a convincing 12- (or 1 string sound out of it, but that was the thing I was least interested in. What it does great is the organ sound, and it also has the octave down thing that was always more interesting to me than octave up (JB's "Come Dancing", anyone?). Here's a noodle-fest, clean guitar to start, then organ, then octave down, then tweaked. Just plain fun.
