I have had an Ibanez Concord 12 string, model #F-302BK for well over a year now and I simply cannot find out anything about it. There is no serial # on the guitar, so I assume that means it was made prior to 1975. The condition of the guitar is as close to mint as possible. The neck is straight and the bridge shows no sign of pulling off. I would love to know when the guitar was made, or get an idea of what it is worth. The person who had the guitar before me had a Fishman Professional pickup installed on the guitar. The work is excellent and you would never guess that it was not done by the manufacturer. Any information would be greatly appreciated.
