I love bass lines, myself. I played glockenspiel in band (don't ask, I dropped out in seventh grade) and given my druthers I would have been a drummer... but bass guitar just does it for me. Particularly White Zombie/Rob Zombie tunes.

I have a scaled-down electric bass sitting in the closet that I still need to take to Wolfie's to teach me to play, but as with most leisure pursuits, I never have enough time.
