hi, ive been playing a bass for like 4 or 5 years now. I learn songs, learn theroy, and try to keep up as many exersises as possible. BUt there is no way i can groove, or jam like jaco or some real hot bass players can. Sometimes i can think of some cool stuff, but other times i feel completley empty, and i find my self just trying to play notes in a scale as fast as i can, (its nothing hard either, its not very challanging) and when im done taht i just feel discusted and very dissatisfied with my bass skills. Anyone else have this probelm? is this Normal? any Suggestions?
