I've got the zoom b9.1 and it's fantastic. It comfortably replaced my huge separates board and is better than the boss in everyway imho, ime. Instant switching, a separate loop, two way pedal, valve preamp, better sounds, easier to use. Just newer and better. And can be had for £250. I've only scratched the surface of mine but I'll sing it's praises all day. And i was all about separate pedals (ive owned three gt6b's too!)
