Hey there, did somebody say.....Wunkay?
As for the OP, if that 81 has an ebony neck, the value will be a bit higher since that's the killer combo. Unless the one on the right (the 81/82) just feels and sounds killer, I'd keep the one on the left.
@Templar is correct, I do have an extremely early Wunkay. Body and neck both dated prior to the official start of production (July 1, 1980). It's in cherryburst, and from the neck pocket that color certainly looks original. I think it was Greg Gagliano (who you GLeeks /BABPers will remember as GGJaguar and others will remember as one of the writers of Ampeg: The Story Behind the Sound) informed me that cherryburst was not an option for sometime much afterward 1980. The serial number is 526. Again, IIRC, they used 500-549 for various one-offs and prototypes, and 550 was the start of production. I sent an email to Dale Hyatt (who reportedly had all the logs for the early years and could sometimes be convinced to dig into the archives), who told me there was no record of that serial number and it was probably a "Leo tester". It does have a tugbar, which has machine (not wood) screws holding it down; there are brass inserts in the body that the screws fit. It's a weird, wild beast....
