Hi, I've been playing bass for about 8 months now, and I can read basic tabs and play quite a few songs but I think im really ****. I Don't seem to be improving, me and my mates have started jamming together (Guitarist, Keyboardist and Vocalist) and I find it really hard to come up with bass lines to go with the guitar. People have told me it's because we don't have a drummer and a drummer would help me out a lot because thats the main person I would work with. But we're looking for a drummer but not much luck at the minute, I really want to play bass good and I practice as much as possible but I don't really know a lot about bass and can't afford a teacher so I just find myself reading tabs and playing songs but like I said, I find it difficult to come up with my own bass lines. All help would be appreciated. Thanks.
