Yamaha's guitar manufacturing began in the 1960s. Aiming to make Yamaha a world leader, the Guitar Research Department was established in 1966, and production of the GC series began in November 1967. In 1968, Spanish manufacturing techniques were introduced. In 1968, Eduardo Ferrer, a guitar maker from Granada, Spain, was invited to Hamamatsu and provided initial guidance on guitar construction. At the time, Mr. Ferrer was an extremely skilled technician who produced the A2 line for José Ramírez. After Mr. Ferrer returned to Spain, Hernandes y Aguado was invited again in 1973 to provide instruction, and the foundation for Yamaha's high-spec GC series, which continues to this day, was completed. Starting with the establishment of the Guitar Research Department and technical guidance, many skilled craftsmen supported Yamaha's domestic high-end guitars, including Mr. Suzuki, Mr. Tsuchiya, Mr. Kaneko, Mr. Kato, Mr. Ezaki, Mr. Harada, Mr. Ito, and many other technicians. The guitar for sale, although the year on the label has faded, is believed to be a GC-5 model made around 1970 at the Yamaha Hamamatsu workshop, featuring all solid-wood construction with Brazilian rosewood. Other models produced at the Hamamatsu workshop included the GC-3 (rosewood model), GC-7, and GC-10 series. The top is made of solid, tight-grained Ezo spruce; the sides and back are made of beautiful quarter-sawn Brazilian rosewood; the neck is made of hard Honduras mahogany; the fingerboard is made of jet-black ebony; and the bridge is made of quarter-sawn rosewood, with side reinforcements, and the heel joint is Italian style. It also provides an elegant and powerful sound with the clear resolution of spruce, and a rich, deep tone that resonates with the wide range characteristic of Brazilian rosewood. More than 50 years have passed since its production, and there are small playing scratches and dents on the top. The previous owner had the top extensively repainted, and it has been used as is. Also, strings for trial playing are strung on it, so you can start playing it immediately. For all guitar enthusiasts, please consider this commemorative guitar, the Yamaha GC-5 Brazilian Rosewood model, which was the starting point for Yamaha.
