No. I had no idea that tuning a half step higher would be more tension than extra high tension strings which I previously believed as well. Along w those percentages given to you by yamaha. Im always intrigued by good info. Please post your pics and play and commentary on the gc82 once you receive bc I have a goal one day to acquire a gc42.

Will do! As to the string tension difference...search for "stringtensionpro" and you will find D'Addario's site for calculating string tension with their strings. Just for fun I did a comparison of EJ45 (NT) to EJ45(raised a semitone) and to EJ44 (EHT) all at 650mm scale.

Here are the results in total tension load:

EJ45 (NT) = 82.81 lbs
EJ45 (+ semitone) = 92.95 lbs ( + 12.2%)
EJ44 (EHT) = 88.67 lbs. ( + 7.1%)

With a little patience, I found the following information on the GC82S on Yamaha's Japan site (translated online...but understandably not all that well):

"GC 82 S" is a model pursuing a new sound with reference to the sound produced by Spanish producer Santos Hernandez and German producer Hauser I and features a rich bass and a bright high tone, and outstanding distantness Is realized.

Features
Pursuing beautiful sounds good sound quality

In addition to beautiful sounds, we have made various improvements to gain rich volume and rise.
The top board has studied the optimum thickness, and it is now possible to obtain a bright sound with a good volume and a good rise. We are also designing a new Hibiki arrangement so that the bass sounds well from bass to treble. In addition, painting on the lower piece and the back of the neck has made the paint film thinner than the conventional one, so that it transmits rich vibration energy to the entire guitar, improving playability. Furthermore, by improving the machining accuracy of the lower piece pillow and groove, the loss of vibration transmission was reduced and the sound rise improved. Both are due to our accumulation of research unique to our company and skill transfer and improvement from skilled craftsmen.

Simple and elegant design while inheriting tradition

Hibiki Hole and Shimomekawa have inherited the traditional inlaid symbols, and made a bright image design."

""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."

Also from the October 2016 catalogue:

"To get rich sound volume and rising, in addition to the beautiful timbre piled up various improvements. Table plate research optimal thickness and, get the large volume and the rise of bright sound. From the bass to the treble balance sounds good, arranged the Symphony bars newly designed. Also painting of the bottom piece and neck back to approximately half the thickness of the coating by transfer the entire guitar a rich vibration energy, improved playability. Improved precision under the stone pillow and grooves to reduce vibration transmission loss and the rise of sound is improved.

Using the GC82S Custom order products ¥ 1150000 (excluding tax) hard case with the finest in Germany pine veneer (front plate), Madagascar rose single plate (side plates). Gc79 and bass, S. Hernandez, Hauser I... pursued new sound, referring to the sounds of the world. Rich bass, treble, far of brighter extends bei model was. String length: 650 mm front: Germany pine single plate back and side panels: Madagascar rose single plate neck: Sedro fingerboard: ebony finger Board width: on pieces of 52.5 mm torso joints of 62.0 mm bottom piece: Madagascar rose yarn: 35G510QC-M treble strings: Augustin Regal bass strings: Augustine Blue label painted full shellac and paint Accessories: hard case"

If I understand the somewhat clumsy and obscure translation, the design of the GC-71 was updated by the original designer (from another document: naniki-san: Mr. Natsuki?) with changes to the soundboard thickness, top bracing, shellac finish thickness (back & neck) and the accuracy of the lower piece (back?) pillow & groove (tongue & groove?) fitting. The results are claimed as an improvement in volume & sustain, projection, bass resonance and evenness, treble brightness/clarity. I cannot make sense of, "the length and shape of the rhinestone stuck on the back of the front plate"? Can anyone clarify this phrase and the "stone"..."pillow & groove"?

I also noted that Yamaha adjusts the GC82S for Augustine Regal trebles/Augustine Blue basses...so the setup is for high tension strings. I'm not sure how the Augustine tensions compare to others such as D'Addario?

Augustine Regal's are one of my favourite strings. Very nice sound. I'm not sure how they rate in overall tension, but they feel very nice to play. I generally play with Augustine Regal Red's, or Augustine Black, sometimes Augustine Red Imperials. Very likely, you will enjoy them. The Regal upper strings feel very "thick" and are nice to press down for a high tension string. The Blue basses are the standard Augustine high tension basses.

Going to be a beautiful guitar!

Thanks Martin...I played on Augustine Black with my GC-10 40 years ago,. but not recently. I think I'll try out a set of Regals with Blue basses and have some fun experimenting until the beauty arrives. This will also help to keep me from fretting (pardon the pun) too much until the GC82S arrives. :casque:

June 2017! :bravo:

I wonder who will be making it? Naohiro Kawashima for the woodworking...Eikichi Yamauchi for the finish...Teruo Nakamura for the adjustment setup? Yamaha tends to use specialist luthiers for different aspects of the build and given the Japanese tradition of service to the art, there are few celebrations of the individual contributions. I'll just have to wait to see who signs the instrument. Segovia's Ramirez (1912) was made by Santos Hernandez (when he worked for Ramirez) and he only added his name with Segovia's permission, in 1922 when he did some restoration of the instrument.

Also of note: the latest Yamaha Japanese catalogue (October 2016) lists the GC-70, 70C and 71 as available for custom order. This surprised me as the Yamaha US site lists these models as discontinued. Translation provided the answer:

"Please note: guitar used Brazilian rosewood rare materials import and export is regulated by CITES, manufactures designed to be used only in Japan. Please note that it cannot be brought to foreign commercial goals."

Yamaha still has Dalbergia nigra in its stores, however it cannot be exported. That may be another reason that Yamaha developed the GC82S/C models and also explains the 28% premium of the earlier series (¥1,600,000 versus ¥1,150,000). If it could be exported it would cost about $2300 CDN more for rare Brazilian Rosewood...assuming the same discount from list that I was able to obtain. :shock:

Last year I bought a Brazilian/spruce from Alan in Canada.Even though the wood was Pre-CITES the paper work involved for both sides was off putting. For Yamaha to export a Brw they would have to prove the wood is from pre-CITES old stock.
Remember Anthony Weller, please help. Contact myself or Aaron Green for details.

Ah so...I can just imagine an instrument getting hung up in customs for months and months while the burden of proof was levied!

Due date is June...so it should arrive in the eighth month from ordering. I am preparing by setting the action on my GC-10 to around the same height and trying out the Augustine Regal/Blue strings that the custom shop uses for setup.

Where does one even purchase the yamaha high end guitars? I thought the high end classical guitar line was all discontinued in 2005 with the closing of the chinese factory?

High end GC series guitars ( at least the GC82S/C & GC42S/C) are made in Japan at the Custom Shop in Hamamatsu. You have to order one which will be made on order, from a Yamaha dealer. My GC82S was ordered in late October 2016 and will be delivered in June, 2017. Finishing alone will take up to 3 months (200-300 coats of French polish shellac). The high end guitars were never made in China. Yamaha started production in Taiwan in 1970 and finished production there in March of 2008 when they moved the factory to Hangzhou, China.

How much are the high end classical guitars by Yamaha?
