This is the Seymour Duncan Custom 5, a classic and highly popular pickup. This one is a rare version with a cover. I used it for live performances for about a year, so there's some slight dulling and signs of use, but it's not as noticeable as it appears in the photos. It is fully functional and has been tested. The item includes only the pickup itself; mounting screws and springs are not included. Please be aware of this.
