I owned one for awhile...had to adjust i/o levels, compressor levels/values, and the footswitch release thing...ugh. It wasn't rocket science, but it took some hunting to find the right answers to my problems. Also, don't expect to rely on the manual for a ton of useful information, as it's unusually thin and (IMHO) underwritten. I'm not huge on studying a bible-thick manual, but I'd have taken one in place of that 'cliff-notes' version of one. As far as the pros, the effects sounded great. I love TC's chorusing, delay, and verb effects. But, at the end of the day, it was just more work than it was worth (for me, that is). I found an old Quadraverb lying around the studio, hooked it up, and presto-change-o... happiness...for a short while. You could find a g-force for around $650 if you look, and a super cheap midi controller and be SUPER happy. That's what I'll be doing, once I recover from my CCV gouge.
