I've got a 1982 Kohno 30 that I've had since it was new. It was a great guitar new, but it's matured into a very, very nice guitar. I think these instruments are currently undervalued, and I've seen them used around $3500 several times over the past year or so. That's probably about half what they're worth. If John Williams played one this fall, the price would probably go up to about $10,000 practically overnight. The only thing that I wish I could change on my guitar is that it's 660 scale--I'd prefer 650 or even 640. I've also got a Kenny Hill Hauser (USA) that's a 640 and it's a breeze to play, sounds great, and is plenty loud.
I have a price list from Dauphin Co. from April 1, 1982. It gives the following model information: Sakurai had the models 7, 10, 15, 20, these were re-named the 7, Standard, Excellent, and the Concert. They were made in the Kohno workshop under his supervision. "They are similar in all respects to the corresponding Kohno models". The model 20/Concert was the signature model. Prices at that time: 7, 780; 10, 1100; 15, 1560; and 20, 1800. The price list does not give any specifications on woods, etc. It is possible that Sakurai made other models that Dauphin didn't import or are not on the list as the Kohno models given are 20 (Concert), 30 (Professional), 50 (Special). I hope this answers some of your questions. (markhobson.net)
This is the guitar that turned me into a real guitar player. When I first started playing I was very fortunate to begin with classical training. I bought this guitar (made by Tama) in the early 70's and it has been a friend ever since. It has solid rosewood sides and back and a very fine spruce top. With a nice wide neck and relatively tall action it is exactly what a classical player needs. It can produce tones that range from subtle to powerful and from harsh to warm. To play Bach on this guitar borders upon a metaphysical experience. Absolutely a wonderful instrument.
