Trying to decide on a looper for practice, not live performance. Want to store multiple loops, so simple loopers like Ditto and Jamman Express are out. Features look pretty similar on these two, dunno if 16 vs 24 bit matters, and 100 storage slots (on RC-3) is enough. Is auto-quantize better on one than the other? Are rhythm patetrns on one better than the other? Is Jamman solo (not XT) a good option if I don't need stereo or ability to connect to other jamman pedals? Thanks for any opinions.
