The '68 moniker on the "68 Custom", and the SF cosmetics, is all pure marketing. There's nothing 1968, or silverface, about it. The vintage BF, SF, and the PCB 65 reissues all fall into the same tonal camp. The '68 Custom is something entirely different, meant to leverage the perception and the market success of the 65 reissue line, IMO. While I generally agree a lot with what Silverface says above ^, I'll add that I like the tone of the reissues just fine, usually. The builds are not similar to the BF/SF at all, though. So, if you want modern sounds, get a Custom. If you want vintage sounds, get one of the others. If you want something easy to maintain that will outlive your grandchildren, get a real BF or SF.
