I've been playing for a year, I have the fundamentals down, and I want to move on. I want a music book that'll further my understanding of bass, and I want something that I can always have with me to check back on... I don't just want to learn the lessons in the book and throw it away. I've heard that Mel Bay's Complete Jazz Bass Book is a great instructional book. Can anyone give me some opinions on what bass book I should buy? Also, I pretty much play rock and blues, but I don't want to be handcuffed to those genres, so if the book applies to funk, jazz, or country, its fine with me, as long as its a good one.
