Everything you need for an awesome electric guitar, except the guitar. ES 335 / ES 339 Complete Hardware Set (Machine Heads, Pickups, Wiring Harness, Bridge, Tailpiece, plastics, etc.). The wiring harness was assembled specifically for a 335 body, but can be modified to fit any electric guitar really. Of course this was pieced together for a project guitar, but I just don't have the time on my hands, or the extra cash on hand for the body needed to finish it. Let em know if you have any questions.
