Another One For The Musicians In Here: StudyBass.COM
I reiterate that I am no musician but this site looks interesting.
StudyBass.com is an interactive, online resource for learning how to play the bass. This site is intended for bassists who want to use the bass in a creative, original way. Anyone can learn to play other peoples' basslines and bass solos. The goal of my bass lessons is to educate you on how to create your own basslines and solos, not just to parrot those of others.
