This is a very rare Ovation adamas acoustic only guitar.This is a preproduction adamas i believe to be serial # 11.There is a piece of masking tape inside the guitar that reads G# 11 which i believe means guitar # 11.The first 26 adamas guitars were prototypes.This is a rare piece of Ovation adamas history built around 1974-75.This has an arched graphite top with f-hole type soundholes.Ovation was experimenting with sounhole configurations to see what would work best on the adamas series.The guitar is a bit crude but playable and sounds good.As you can see from the pics below the top is black but never finished or painted,just raw graphite.The binding was never finished and you can see the fiberglass and resin on the pic with the side of the guitar .The fingerboard was not completely finished at the bottom but all frets are there and guitar is playable.There is also an access door on back held on by tape.The soundhole was there to acces braces and to shave them for voicing the guitar.The case is an ovation brown hard shell case that is nice inside but some of the brown plastic has broken off and you can see the stirofoam.All latches work on case..email or call me with any questions before you bid.I can give more details if needed.buyer pays fixed shipping cost of $40 to USA.I will ship international but must deposit funds directly into my account.No cashiers check or money orders for international shipping...
