I got another copy of Bill Milkowski's Jaco book for Christmas. My in-laws got it for me. I already have it and have read it a couple of times. I thought I would see if anyone has a bass instruction book that they would just like to trade even up. I would love a book on building walking lines. I have been playing for nearly 15 years, but have never "learned correctly" so books on theory would be good. Books on scales, modes, chords, etc. Soloing books would be good too. I know Bunny Brunel has one out that is supposed to be good. Let me know what you have. I am trying to do things correctly . . . finally.
