i just used it for a rockabilly recording and i thought it sounded pretty good. i took a little playing around with the settings to get the slapback i wanted but it was in there. i also forgot my power supply and killed a brand new 9v is about 5 hours :smack:
I have successfully convinced one of my coworkers to get one though. by judging the soundclips on the line 6 website, he fell in love with the 63 spring and the cave.
