[Profile]
Yamaha (founded in 1887 in Hamamatsu City, Shizuoka), the world's largest manufacturer of musical instruments and boasting an overwhelming market share in the musical instrument manufacturing and music business alone, was also an early proponent of the classical guitar. In 1966, Yamaha established the Guitar Research Department and began research and development of handcrafted guitars in order to stimulate the classical guitar market in Japan. The following year, Yamaha invited Eduardo Ferrer, who at the time was a mentor in Granada, Spain, to provide guidance on traditional Spanish construction methods, and in 1973, invited Manuel Hernandez (Hernandez y Aguado) to provide technical guidance. The result of these intensive training programs was the Grand Concert (GC) series, which continues to this day as a high-spec series of Yamaha classical models.
