Ok, here's the deal. I've had a bass and amp for almost 3 years now, and I've really not progressed as a player at all. That's probably because I've done nothing but play parts of tabs from pre-existing songs. My goal is to get to the point where I can just pick up a bass and play something that sounds decent. Now the catch. What would you suggest I do to get to this level without taking lessons? I'm a college student so I don't really have the time or money for lessons. That and I feel a bit old (almost 19) to be just starting on lessons. So what are your suggestions for learning to play well and training my ear to pick up basslines from songs? Any help would be greatly appreciated.
