I play bass because it's fun. I'm primarily a guitar player, but I like to thump around on bass too. Most people wanna ham it up on guitar instead of holding down the rhythmn, so Bassists are a little harder to come by than guitarists. It helps to be able to thump on four as well as pick on six in order to take advantage of situations as they come. Plus it's that much more gear to spend money on, LOL!
