I've owned at least 4 looper pedals, none of which have I kept as they're either too complicated or compromise the signal too much. This has both problems sorted - dead easy to use and doesn't interfere with your sound. Once you've sussed it (10 seconds max) you can build up layers or jam to your heart's content. I've already used it for a couple of solo gigs in the pub and it was absolutely brilliant - don't need a second guitarist to sound like a band. Honestly, this and a tubescreamer and you're sorted - an absolute must for every guitar player. Be interesting to see the reaction of the other manufacturers that have gone down the kitchen sink route - Line 6, Roland etc, 'cos this thing is a game changer.
