does the RC20 have the same "glitch" as the RC50? I was going to get an RC50, but now that I know about the problem, I am back to the drawing board. I'm looking at the Jamman and the Rc20 now, as entry level loopers. I really like that the Jamman has usb and flashcard memory. But how do you get stuff out of the RC20 if you want to? Michael C.
