Can anyone tell me anything about this specific Bluesbird posted on Ebay? I know there are a couple specific infamous Bluesbirds around that nobody wants to touch, and I don't want to bother if that is the case with this one. Any obvious red flags anyone sees here? Any information at all will be very well appreciated!! http://www.ebay.com/itm/Vintage-1973-Guild-M75-Bluesbird-Black-Solidbody-/151558873629?
