Re: CAN YOU TELL ME WHAT THIS IS?
Almost definitely a mutt, note that its missing a neck bolt, the pickups aren't original, neither is the trem.
The serial number on the neck dates your guitar to 2000.
Neck has been scavenged from a much higher end S series too, since there was no prestige S series in that year (2000) that came in that finish, nor was there one that came with HSH pickups in a prestige form, the closest would be the non-prestige S470. In fact, that finish doesn't exist in the 2000 lineup at all.
