Re: looper pedals!
I have a DigiTech JamMan --- it is pretty rad.
I LOVE LOVE LOVE several things about it:
1) It has an XLR mic input, so I can loop vocal parts as well, which I do, all the time. So fun to harmonize with yourself.
2) It has a USB in/out, so you can literally drag and drop the things you record to your computer (never have to lose a loop again!) AND you can drag and drop stuff from your computer onto it, like backing tracks you downloaded, or simply a song you like and want to play with. AWESOME.
3) Storage space: I have a 2GB card in mine, which means SIX AND A HALF HOURS OF AUDIO! It's insane, and Compact Flash is hella cheap, so if you were a solo musician, you could keep multiple CF cards around if you had a really long set (remember that 1 hour worth of music with 6 parts is 6 hours of audio)
4) It has individual gain controls for the mic signal, the guitar signal, the beat / click signal, and the overall loop level that leaves the box and goes to your amp. SUPER TWEAKABLE.
I searched high and low for the best looper in the reasonable price range (i.e. I wasn't looking at $$$ Boomerangs and the aforementioned Oberheim) and this is what I found to be the best for the buck. I love BOSS pedals and have a lot of them, but from my research, this is the looper to have!
P.S. I can run it in my effects loop, not even engaged and looping, but just as a volume control, so I can turn the volume on the JamMan way down and crank my amp's clean channel and get sa-weet clean sparkle drive --- this is an old Fender Hot Rod Deville trick!
