Okay i have come to the point that i realize i need to learn theory. I have already learned the basics from several different web sites and beginner books but i want to go deep into the theory and see how everything works together. So that brings me to my question for all of you more experienced people out there. What book should i buy on bass theory? i would like it to be very complete and preferably have tabs (I'm still working on the reading) but not a must, and i would like it to have some kind of practicle practices for everything that you learn so that you can apply it, preferably a cd or something like that to play along with. Any advice would be helpful. Thanks!
