Last month, I took the risk of buying a Yukinobu Chai guitar (Tokyo, 1981, No. 20) on the internet. It was not very expensive and I was curious to find out.
It has cedar top, Indian rosewood back and sides, ebony fingerboard, Gotoh tuners (like Kohno) and standard dimensions (650 mm, 52 mm), slighly domed top and back. It has 7 very thin braces, and an asymmetric bracing pattern.
It has been played and the top has some scratches, but the neck is straight and the fingerboard and frets are allright. I am surprised about the well-balanced sound and the very good intonation, it is extremely correct up to the highest notes.
So, it is obviously hand-made, excellent work, and can compete with other master guitars. Most of all, I like the sound.
It is really different from the Kohno and Nobe guitars that I have.
Inside is a small label "Niibori Guitars", I do not understand what this means, although there is a dedicated WWW site in Japan.
Best wishes to all,
