Yamaha invited a famous guitar maker from Spain in 1967 and, incorporating Spanish guitar-making techniques, produced and sold authentic models GC-10, 7, 6, and 5 at a particularly high price. This item also follows that lineage, and the quality of its handmade construction is outstanding. It shows little sign of use, and there are no noticeable scratches. It's in excellent condition for its age. The neck is almost perfectly straight. Scale length: 660mm Neck width: 52mm String height: 3.5-3mm
