I bought RC-20XL last Christmas, and i like it so far, but it would be nicer if i can record more than one loops simultaneously. I know RC-50 does this, but I dont have it yet. Well, I just found another looper, Digitech Jamman, that seems pretty cool. Do any of you use this looper? It has many cool features that RC-20XL doesn't. Maybe I should have bought this one. But does this looper allow to record more than one loops at the same time? Which one do you guys think better?
