I mean audio looping, not effects loop switchers. Like the Ditto Looper or Ditto Looper X4 from TC Electronic, or EH Nano Looper 360. I tried a search but didn't find much. The main thing I'm interested in doing is laying down a groove for oh say 8 or 16 bars, then picking up another instrument to play over that. I'd want to do it live in a band situation. I like the idea of overdubbing and undo, and some effects could be fun but the reverse and 1/2 speed type effects don't do anything for me. I'm a bit of a tone snob so any tone suckage will be looked down upon. What do/would you use? Any of them particularly suited (or unsuited) for bass? Cheers!
