It is in fact kind of hard to incorporate into music. I found its very usual in tandem with a Small Stone (SS before the Poly). I use a Les Paul with a P-94 in the neck, and I can use the Polyphase to dial in certain frequencies, like using a wah pedal, to get very Fender like tones. The square wave is interesting yet hard to work with, with the exception of higher rates. I also appreciate how waters the Saw tooth mode is on LFO mode. And to touch upon what you said, I like the ENV mode with the faster setting as I found the slow too subtle. What were some of your tricks to make that sound good as well as other general things about the Polyphase?
