This is an epic journey and a revolutionary concept teaching fretboard proficiency, combined with improvisation and mental practice. It's a workbook! Have pencil and your bass ready.
Great system. The author wants you to think! So, not everything is spoon fed to you. Instead the patterns and examples are laid out in one key, and from there you can work out the other keys, etc., this increases the memorization and allows you to "visualize" as you reason it out.
