Hi everyone....i stumbled onto a sale of this les paul and am curious about the asking $....the guitar is all black with what appear to be “mirrored” pick guard and pickup rings. Serial looks like I 45xxx... With a sticker at the top of the neck volute that say “550”...he is asking $550 for the guitar and a hardshell case.....it looks to be in decent condition.....thoughts on the price? Any comments on this would be greatly appreciated. Thanks!
