I purchased this book at a bookstore several years ago. It has been stored on a bookshelf since then. The condition is clean. Thank you. [The following is quoted from the publisher's website] Everything you need to know about the structure and mechanism of the electric bass is in this one book! Written by Yutaka Takeda, author of the long-selling book "Electric Guitar Mechanism" which first appeared in 1992, this is the birth of a new bible for bass players and bass makers. The structure and mechanism of the electric bass are explained in detail, broken down by category such as woodworking and electrical parts.
