Osamu Nakade is the son of Rokutaro Nakade, a rare guitar maker who produces various types of guitars, including classical and flamenco models. While inheriting the techniques of the Nakade school, he also creates works that are not bound by convention, using his own skills and ideas. Guitars made by Osamu Nakade are handmade, so the number of completed instruments is small, making them valuable and not often seen. The guitar for sale was made in 1980, a full-fledged classical guitar made by the young Osamu after he left Rokutaro. It is a prototype classical guitar meticulously crafted using high-quality materials of the time. The top is a solid spruce soundboard with a tight, natural grain; the sides and back are solid rosewood with a tight, straight grain; the neck is hard, dense mahogany; the fingerboard is jet-black ebony; and the bridge appears to be straight-grained rosewood, with a German-style heel joint. The acoustic effect of the spruce and rosewood produces a beautiful, elegant, and clear tone. Although 45 years have passed since its production, there are few scratches and dents. There is one crack on the lower left of the top, which the previous owner has repaired with paint. Overall, it is in good condition. Also, strings for trial playing are already installed, so you can start playing it immediately. For all guitar enthusiasts, please consider this rare and valuable Osamu Nakade Concert C15 classical guitar, of which few were made.
