So I'm being offered a 1996-97 American Strat for $550. It has the black finish over the top contour on the back which I found kind of strange and made me wonder. I already bought a guitar today and bought a newer American Strat a week ago. I really don't need it but it seems like a really good deal. Are these good guitars and if I find I want to get rid of it, what's the resale on these?
