Oh man, that is painful to look at.

I have to wonder if it was in a flood, or a roof leaked, or something. I can't imagine someone just letting it get this bad over an extended period of time.
Maybe at least the pickups might be salvageable? Guess that's one good thing about the epoxy-encased pickups - at least there's no exposed metal to corrode.
That's still a pretty decent chunk of change just to get some replacement FAG-170 pickups though.
