FYI: Rich Appleman and Joseph Viola also have a similar book: "Chord Studies for Electric Bass." I'd be willing to bet that the material is similar to the trombone book especially since they both have the same co-author.nice thread... @BrotherMister, thanks for the review of the materials. Several times you mention a trombone book that Jeff used as the basis of the chord tone package. Can you tell us the name or author of that book?
Now I start with 15 minutes practice. Just G major scale up and down the neck, then Mode also up and down the neck.
