1989 Greco Mint Collection SS-85S? SG
Just got this and sure enough the solder is original as too is everything else.
The pickups routes are 3 individual routes perfectly made for mini humbuckers with the ear/tab routes and all.
Nothing in any of the catalogues for this model that I have been able to locate.
Perhaps an order made model?
Who knows but it is killer and the pups sound awesome.
