Hello I can answer most question on anything to do with Yamaha acoustic guitars, as well as a range of other Japanese made vintage acoustic and classical guitars. As a collector and trader I have a pretty good knowledge of trends and current values. As a said, Yamaha's are my area of specialty, particularly any made at the Nippon Gakki, or Japanese factory.
