This is a Yamaha Bossa Nova guitar. It's a very rare guitar with a low production number. It appears the bridge has been repaired. The neck is straight. String height is 2.5mm at the 1st string 12th fret, and 3.0mm at the 6th string 12th fret. A semi-hard case is included. It has a special finish that maximizes bright resonance, producing a crisp, bright sound suitable for Bossa Nova music. The design also evokes Bossa Nova, with inlays inspired by the light and greenery of Brazil.
