This is a set of three books I obtained used. They show signs of wear, such as yellowing, folds, and wrinkles, but there are no noticeable tears or missing pages. Also, the books have been cut, so there are no spines. Especially for jazz bass beginners, Koichi Osamu's "Standard Bass Course" includes not only TAB notation but also the history of the songs, performance interpretations, and other useful knowledge for playing bass on standard songs. Please consider purchasing if you understand that these are sold as-is and are non-returnable.
