I don't know much about this guitar, but from what I can gather, everything appears to be original aside from the pick ups. There is a sticker underneath the pickguard that matches the serial number on the neck. Not sure exactly what pickups are in this but they look like vintage Dimarzio SDS-1's. They sound great to me. Based on the hole in the pickguard, I would assume there was some sort of switching system installed at some point that has been removed. I was told the previous owner owned the guitar for roughly 40 years. There is a line on the back of the neck where the headstock begins, not sure what it’s from but you don’t feel it when playing. Looks to be purely cosmetic. The guitar will need a setup, I am not comfortable setting it up on my own. Comes with original hard case. selling at a low price because of the uncertainty and due to the fact that it needs a tech to do some work on it.
