In my recent quest to learn all that I could about playing Bluegrass Bass I discovered the following bass-related sites that I thought were worth sharing. The first is a great forum akin to Talkbass.com comprised of players of all levels. The next two are free lesson sites that are great if you are just getting started. The last two provide more focused and in depth lessons for a monthly fee.
Bass & Blugrass: A Forum and Message Board for Bluegrass Bass Players (and others too)
How to Play Bluegrass Fiddle: Cool little homegrown site by Warren Yates
Artistworks Academy of Bluegrass School of Bass: Slick new site offering Bluegrass lesson’s for more than just bass
