Many thanks for the link! My 1971 Yamaha GC-10 was made by Hideyuki Ezaki. Great to see he is still plying his craft as a luthier.
Is your GC-10 is the one made from 1967- 1971 with BRW or it's a GC-10d? :D

How does your GC10 compares to your GC82S?
From my GC82S thread:

"The guitar is lovely...very refined! Beautifully built and finished. More dynamic range, reach, i.e., projection, tone colour, easier to play, etc., etc. My wife noted immediately that my playing was noticeably more musical. She was listening from a few rooms away and heard a "bigger" voice and increased interpretive subtleties.

The trebles are bright and singing, yet sweet; the midrange is clear and vibrant and the basses are resonant...all with great sustain. The intonation appears to be very good and so far I have experienced that the guitar provides an almost effortless access to musical interpretation of the pieces I play. Even though not yet “broken in”, the instrument feels very alive and communicative. On this last point, it feels as though there is a soundhole in the upper bout (a modern addition to numerous classical guitars which provides more feedback on the sound to the player)...yet, none is needed.

For now, my experience is very much like that of my wife's when she first played a Steinway Grand piano: Wow, I can get so much more of the music in my head and heart out through the instrument than before. Where did all those nuances come from?! This will improve with age... :shock: :D

More to come on tonal character, etc."

So...GC82S:
1. Better construction, marquetry, finish, more delicate and refined.
2. Much bigger voice, dynamic range, projection, tone colour range.
3. Easier to play and requires much less effort to create dynamics and tone colour shifts.
4. More warmth and this may increase as the strings are still new.
5. Comments on tonal balance/matching, clarity of voices, etc., to come

My GC-10 is a lovely instrument with plenty of character...the GC82S is simply in another league.

Yamaha sent me a gift with my GC82S: "The History of Yamaha Guitars" and it contains some interesting history on the GC-5-7-10. Yamaha's luthiers at the time had no experience in performance evaluation and this is how the 5-7-10 designation was accomplished:

Yamaha History GC-10_2 small.jpg
The book also notes that the Argentine guitarist/singer Atahualpa Yupanqui played a GC-10:

"Atahualpa Yupanqui is the Maestro of the Latin American folk music from Argentina. He visited Japan in the late 1960s. After meeting with the designers, he left with his hand-selected GC10, which was later used to record his visit-to-Japan commemorative album."

Beowulf, I’m very glad to see you found that your GC82S meets and even possibly exceeds your expectations. It has to be very reassuring. In my case, I don’t know if I would ever be able to order a guitar for several thousand doollars without having tried it first. The mere awareness of the possibility that I might not like how it sounds or how it feels, would just make me extremely nervous.

Your descriptions of the combination of richness of sound and comfort of play are very similar to how I feel about the GC42S, though I imagine yours may have a bigger sound.

I was checking the specs of all the current GC models on the Yamaha Canada site and was very surprised to see that the 82S is supposed to have a significantly smaller body lenght and width than all the others in the current GC line (including the 82C).

This is the specs page:
https://ca.yamaha.com/en/products/music ... oduct-tabs

I have a feeling there may be some mistake in those numbers. The body of the 82S is supposed to be 6 mm shorter in length and 4 to 5 mm narrower in width than all the others in the current GC line. (Really?) And yet the total length appears to be the same for all of them. I find this very odd. Can you confirm those numbers are correct?

Anyway, congratulations on your purchase. I’ve been meaning to take some pics of my 42S (also signed by Naniki) and post them here, and I should get around to it in the next few days.

Thanks Francisco...I am still in a state of amazement. I did a great amount of research before I decided to order the GC82S and had wanted a GC71 for many years. I have an excellent audiophile sound system and was able to hear the sound of the GC82S from 4 recordings of good quality from the internet. I was also able to get a take on the differences in the sound compared to the GC82C. My wife's excellent ears helped a great deal and she felt strongly that the GC82S was the model that best suited my musical preferences. I did not prefer the sonorous, warm, romantic "Spanish" sound of the GC82C...though this may be exactly what others are looking for. I like a clear, resonant and rich sound that is well delineated and serves renaissance, baroque, counterpoint and earlier music. I also listened in depth to the sound of Segovia's Hauser and Akio Naniki (the designer of the GC82S and the GC71) specifically used that sound as a tonal reference (as well as Segovia's 1912 Ramirez/Santos Hernandez) when he designed the GC82S. Later on in his career, Segovia moved to larger instruments with a sound closer to the GC82C. He actually performed in the concert hall with the Yamaha GC71 late in his career and also chose a GC70C as a practice guitar for his cottage. I knew that Yamaha luthiers were superb craftsmen and that the woodworking, marquetry and finish would be second to none...unless you have $20,000 or more to spend.

I have not heard a GC42S, so my comparisons are with my GC-10. The voice is much bigger: a simple test, just open the case and strum across the open strings. I did this with the GC-10...very nice resonant and pleasant character. With the GC82S...WOW, full of life, power and rich character. This is a kind of a mini test for projection.

The numbers are relatively accurate (though the total length is off) and will vary from instrument to instrument. Yes, the body length and lower bout width are accurate. Here are the dimensions of my GC82S:

Total length: 979mm
Body length: 484mm
Body width (lower bout): 366mm
Body width (waist): 240mm
Body width (upper bout): 282mm
Body depth: 92mm-101mm
Nut width: 52.25mm
String spacing: 11.8mm (saddle); 8mm (nut)
Scale: E - 652mm, e - 651mm

I look forward to seeing the pictures of your GC42S!

Interesting document, expect that it's not entirely true :) The models to come out of the workshop at that time was GC-3, GC-5 and GC-7. I owned a GC-3 from 1967 for example. Also the woods used was a direct indication of what model it was. GC-3 was Indian rosewood while GC-5 and GC-7 was Brazilian for example.

The article did not include any reference to the GC-3 and the GC-5, GC-7 and GC-10 all used Jacaranda. The GC-10 is listed in a number of sources as released in 1967...do you have a source to the contrary Jon?
y1967_gc_3-5-7-10_l.jpg
The GC-3 had a different rosette, however it does appear that the GC-7 & GC-10 had a similar head.

I have found two other differences between the GC-5 and the GC-10 other than sound quality and head:

The GC-10 has a scalloped nut and the ezo spruce top was stained a dark reddish orange...apparently not so on all the GC-5s (perhaps this had changed by 1971?):
GC5 1971.JPG
"C'est un instrument à la sonorité brillante et résonnante dans les aigus, grave et majestueuse dans les basses, avec des médiums très présents et précis. La troisième corde est d'une tenue exceptionnelle et il y correspondance quasi parfaite avec les notes identiques jouées sur la chanterelle. En fait, son barrage léger sur une table assez mince mais pas trop, lui confère des qualités alliant tonicité et substance à une bonne longueur du son. En fait, on se situe là dans un registre très proche de l'école Espagnole traditionnelle (Torres, Simplicio, ...). Cet instrument possède une sonorité magnifique qu'on ne retrouve plus sur les instruments d'inspiration espagnole depuis l'arrivée en force du "red cedar" dans les années 1970."

Rough translation for those who do not read French: "It is an instrument with brilliant sound and resonant in the treble, serious and majestic bass, with mediums very present and precise. The third string is exceptionally strong and there is almost perfect match with the identical notes played on the chanterelle. In fact, its light dam on a table rather thin but not too much, gives it qualities combining tone and substance to a good length of sound. In fact, we are in a very close register of the traditional Spanish school (Torres, Simplicio, ...). This instrument has a magnificent sound that we can not find on Spanish-inspired instruments since the arrival in force of "red cedar" in the 1970s"

Yup...the same, except my GC-10 does not have the tuning fork logo and it is more rectangular:
