I personally don't think that the newer reissues sound much like the originals. They are a good bit clearer in tone, IMO. I restrung a SG reissue with Pyramid flats and it plays very nicely, with very little effort. They are nice instruments with a fair amount of vintage vibe, but with a little modern clarity added in.
