Yes...it is an interesting interview but could have been much more informative with a Japanese/English interpreter. This would have allowed Akio Naniki to be far more articulate. Thanks for the synopsis!
From the link you posted above (great source!) under"Pick up" there is much that confirms his interview coments:
Yamaha's Japanese site has articles on the development of the GC-70/C/, GC-71 and the GC82S/C (I do not read Japanese, so the interent translations are clumsy):
A discussion between Toshio Kato and Shomura Kiyoshi in which the evolution of the sound is discussed. Shomura Kiyoshi felt that the GC-30A needed improvement in the bass firmness and sustain and Toshio Kato confirms that this was one of his goals in working to develop the GC-70 over a period of 9 years.
Segovia actually chose a GC-70C for his collection.
Information on the changes made with the 82 series relative to the 70/71 series:
"We made improvements to make the sound rich, the sound rise well, the sound that sounds good and brighter.I think that it became the sound which can feel the gloss and color feeling also in the clear sound which is the feature of Yamaha's classical guitar "Akio Naniki, development manager.
"GC 82 S" is based on "GC 71", "GC 82 C" is based on "GC 70 C"
"GC 82 S" and "GC 82 C" were added mainly to the "bonding and accuracy of woodwork", "the thickness of the front plate", "the length and shape of the rhinestone stuck on the back of the front plate", "painting ". In guitar making, all processes influence the tone from selection of materials, but the tone will change not only depending on how it is made but also by the person who makes it. Along with the trend of the times, new materials, adhesives, paints, etc. are born and mechanized, but Yamaha continues to keep the traditional recipe."
"I showed prototypes of" GC 71 "to Baden Powell in 1984 when I was in Germany and Hamburg, he liked it very much, then after he wrote a letter and said," There is a soul in this guitar It can be asserted that it is going down.It was written that it is a real guitar. "It was reunited twelve years later, but I was deeply moved by being told the same kind of words directly." Mr. Naniki)
Core sound with transparent feeling
Tone color change due to nail touch is large
The sound change due to the impact effect is large
Bright and warm sound
Good sound response
The treble is slightly thick, and it is louder than the pine
The change of the sound due to the impact is small and the degree of completion is high
"GC 82 S" is a model pursuing a new sound with reference to the sound produced by Spanish producer Santos Herminandez and German producer Hauser I and features a rich bass and a bright high tone, and outstanding distantness Is realized.
"GC 82 C" realizes the original sound with reference to the sound of the Spanish producer Manuel Ramirez, features a sweet, bright and soft sound, realizing rich volume and excellent response.
GC70 It is a vertex model of pine tree material of Yamaha original sound which made carefully selected German pine veneer as a table board based on traditional Spanish production technology. A delicate tone with transparency drifts the fragrance of Spain, enabling expressive performance.
GC70C It is a rice cedar model of GC-70, using carefully selected rice cedar veneer as a top board. As a vertex model of Yamaha original sound rice cedar, it features sweet, bright and warm tones. It was added to one of Segovia's ten collections. Excellent response and rich volume make dynamic representation possible.
GC71 It is a unique approach model that S. Hernández and Hauser I's sound are sublimed by Yamaha's design and production technique. We realized a heavy bass and a thickly extended treble, Andrés Segovia is also acclaimed. It is excellent in far reach and makes your performance stand out even at the concert hall.
Mr. Naniki used to join in the production of the guitar used by João Gilberto before and was also a super developer who also worked on the development of silent guitar! It is! Actually Mr. Naniki, developer of the model "GC 71" 29 years ago. It is said that he was away from the development of classical guitar several years ago, but in the meantime he also watched and played various guitars as guitar enthusiasts, and he seems to incorporate ideas born there into his new work.
Legend of Brazilian music world, Baden Powell (1937-2000).
Picture with "GC 71".
Also, his son Marcel is a masterpiece for the future of Brazilian music.
What kind of music will he deliver to us that he has a "GC 82 S" from now on? This is not the end of the story. Baden Powell will leave the world in 2000, but Mr. Naniki could hand his new work "GC 82 S" to his son and guitarist Marcel Powell. And Marcel Powell said, "I can not believe it was easy to play and seems to have been made for myself" to Mr. Naniki.
