that is a nice looking s-500 and appears to be a late build, 1st style body. craig is right to point out the aftermarket pickguard which looks like plastic. while the pg looks pretty cool the orginal metal pg (and control plate) the guitar would have come with was part of the grounding system (at least on the early ones) which may or may not make a difference to you. you might be able to get a metal pg made for it (Tone Guard?) or you might like it as is but i did want to mention it. i have a Skyhawk with the
fine tuner bridge and it works just
fine and plays pretty much like a regular DF setup. if you haven't already, check out Greg's site for some guitars and close ups of the different versions of the bridge. There are also a couple of completed auctions with Skyhawk's having this setup.
