wow - there's a mouthful... Duncan Designed 2 band, bass & trebel with blend. The blend is wired for the coils of the Duncan Designed MM style humbucker. All wired up except for the battery harness, whioch is included along with the wiring diagram. I did the diagram as I pulled it. Wanna hot rod that OLP ? or ? $80 / obo shipped & Paypal'ed conus will get it done. It is a decent setup pulled from a Samick Royale 'Greg Bennett' hollow body that I Dark Starred.
