I've been reading and listening, but there aren't a lot of demos on bass... I want a really good-sounding phaser that can nail that Pink Floyd chewy thing, has no volume drop, and can also get crazy as needed. Getting crazy is a secondary consideration. Mainly, I want to get THAT classic sound, but with more versatility, blend, feedback, etc. The three that I'm looking at: HBE Psilocybe VFE Enterprise Mojo Hand Nebula IV Help!
