If you go to the
TalkBass on YouTube thread, I've got a few videos of me goofing off with my RC-20XL. Look for the worst videos and playing in the group.

Something about recording makes my mind and fingers go blank. *shrug*
The vids aren't really all that special, but I agree about how much fun they are - and when you can throw a multi-effects pedal in front of it, the sonic possibilities are pretty endless.
