You can remove with the Boss-RC20 xl. We got the normal version: Recording time: 5.30 min, 10 phrases - 350€ The xl Version: Recording time: 16 min, undo function, 10 phrases - 350€. If we knewed it before, we would have bought the other one. But there isn´t even an AC Adaptor with it. Just Batteries. For the Record: 2 sides full of Samples. No Beats, just samples. I think its a good record.
