The Billy Gibbons Ultimate SG was a limited run produced for luxury retailer Neiman Marcus in 2015. The purchase included tickets to see ZZ Top and having the guitar personally delivered to you backstage by Gibbons. The hardshell cases were hand-painted by Nashville-based artist James Willis. Only 10 units were produced, although a few prototypes were later sold off. In 2018, another 5 were built for employees without Gibbons' name attached, in various different colors.
