Freddy,
I just want to let you know that I've written five bass books for Hal Leonard, which you might find helpful.
Funk Bass, my first book, devoted to the slapping technique.
Funk/Fusion Bass, my second book, focuses on finger-style funk.
Rock Bass is my third book.
Blues Bass is my fourth book.
My BRAND NEW BOOK, scheduled for release at the January 2009 NAMM Show, is called BASS GROOVES: THE ULTIMATE COLLECTION. It covers just about every style you'll ever need, including blues, jazz, rock, funk/R&B, reggae, country, latin and much more.
Will Lee, who wrote the foreword, called it "the most important book since Standing in the Shadows of Motown!" It's also endorsed by Stuart Hamm, Brian Bromberg, Bob Babbitt, Steve Bailey, Alexis Sklarevsky and many others.
If anyone has any of my other books, let me (and everyone else) know what you think. I'm happy to answer any questions. Thanks!
Jon Liebman
