1965 reissue?
Are you’re referring to the ‘64 Standard reissue w/Vibrola? Other than looks, this is a completely different SG. Main difference for price is that it’s a Custom shop build. That in itself has always commands the higher price tag. As for differences in the instrument, there are many. All the woods are hand picked and of higher quality. Different shaped neck and vintage frets. Also the pups are unique to this build and wiring is different. There’s a few other things I’m sure I missed.
And oh, the crown on the headstock is in the correct location.
