I've got a JamMan and have been using it now for the last year and a half or so for practicing at home. I've also got a 2GB flash card as a "hand-me-down" from my old digital camera (new one uses SD cards).
I'm beginning to work with a laptop based setup for more versatility. I'm using a:
â€¢ Macbook Pro (my old work laptop at home for work related stuff but when not working...)
â€¢ Presonus Firebox
â€¢ Behringer FCB1010 Midi pedal board
â€¢ Logic Express
With this I can directly use any of the loops that I have access to or software instruments to build backing tracks. I'm setting up the FCB to control Logic to start/stop recording or playback, switch loops, change tempo, change volume, etc.
I'm not sure if I'm going to keep the JamMan after I get this all set up and working. It's nowhere near as flexible but it is a lot more portable. However, right now and for the foreseeable future I'll just be using the looper at home as a practice tool. The Macbook setup is also a decent lightweight recording studio.
