I just brought an old EHX Poly Phase - thing is, it's broken and is round at my Dads right now while I'm waiting for a schematic so he can try to fix it. Does anyone have one of these pedals or has anyone used one? I want to know if it works OK on bass, if it was specifically designed for guitar and how effectve (no pun intended) the effects are? For those who've never heard of a Poly Phase: it has an envleope, phaser and distortion all in one - sounds cool?!
