I've really been thinking about picking up a uni-vibe. big hendrix fan and big phaser fan. i searched and couldn't find any big review threads or people saying they do or don't like them on bass. i would like to know who has tried it on bass and if it sounds cool. here are the models i'm thinking about original vintage uni-vibe (why not) foxrox aquavibe sweet sound mojo vibe mojo hand luna vibe fulltone deja vibe (not a big fulltone fan though) I definately want one with an expression pedal to control speed since that's the essence of the original.
