I've been looking into a looper for a while, just haven't been able to justify the money for it yet. Theres a somewhat local musician in my area that uses a looper and does a one-man-band kind of reggae-blues thing. He is phenominal, and and has truly mastered effects/looping imo, all with an acoustic guitar. He would play a drumline, bass, some guitar rhythm, and loop them overtop each other, then solo/sing atop it all. His name is George Wesley, if you would want to check him out.

The Digitech JamMan was the pedal I had been looking at, but the Rc20 can be had for a much cheaper price, and may be all that one would really need. I did a quick search on eBay and found that the JamMan could be had for around 250, and the Boss for well under 200. Some single-effect pedals cost that much!

I'll have to put this on my list of "things I want but don't have enough money yet"....
