If you get the feel right, you can add a lot, but if you don't get the feel right, things will not go well for you. One night, I sat next to a the bass player in a good bluegrass band-- I was amazed at how much he was able to do without losing that solid bluegrass feel--

As a former country bass player, I found that the most important thing was to get the biggest and cleanest sound possible out of my set up--simple bass lines are not necessarily easy to play, particularly if you care about technique--
