So far I've never read anything bad about this, except that it is not true bypass and is expensive. Can it do univibe to Phase 90 and beyond like so many people say? Being able to switch between 4,6,10 stages sounds like it should be super versatile. The lack of true bypass is my worry, because I'm already using a non-true bypass Digitech PDS-8000, and am adding an Arion SCH-Z any day now too. One of Maxon's 10 stage sound sample make me want it because it reminds me of Ayreon's Prog Metal music, and its a sound I don't think I've heard from other guitar phasers ... excepting Moog which is too big and complex for me.
