Ibanez Concord 646 12-string guitar. The guitar comes from a period before serial numbers, dates approx. 1973-1975. In beautiful condition. This guitar is a Martin copy originating from the best years of the Ibanez company. The top of the guitar is made from fine close-grained spruce. The back and sides are made from rosewood, with beautiful visible grain (see photos). The bridge and fretboard are also made from rosewood. The wood used is what gives this guitar its warm sound and volume. The guitar is like new. There are only two small dents in its lacquer on the bottom (caused by a bad stand?). See the photo of the bottom. The guitar comes in its original case.
