Celebrity-Owned Guitar!

I just saw a listing on Ebay...sort of ran like this..."Celebrity-Owned Guitar. Hank 'Carter' McCormick, played this guitar on many sessions. If you have heard ELO's "Roll Over Beethoven", then you have heard this guitar!" Now this is all made-up, but I have seen these guitars listed on EBay over and over. I have also purchased a guitar that was supposedly all-original, and instead the guitar had been put together inside by a refridgerator repairman. Truth be told, I lucked out with many other guitars, that actually were from artists, and more famous than Hank. What helps with the celebrity provinance are things like paperwork. Also PRS signs the name of the artist in the pickup cavity usually. Real artist guitars are rarely signed by the maker on the outside...to the arist. Early Santana guitars had little notes from Paul Smith on the reverse of the headstock, but unless it is Jerry Garcia's guitar, made by his friend, it is usually not done. Some models have special features that were only made for the artists... like Richie Sambora's 'star' dot-markers on the fretboard. I recently saw a Buck Owens Tele for sale on EBay... with the three-color scheme Buck used to have on his guitar, when he was with his Buckaroos... but honestly, that could have been done in a garage in Fresno in 1974.... Caveat Emptor... (I remember the term from an episode of the Brady Bunch... Mr Brady says it... it means 'Buyer Beware1').
