This is a really early Yamaha Grand Concert model.
This greenish color label was replaced by brown and gold label shortly after 1970.
It is a rather rare guitar.
Yamaha did not make too many of these, partly because they were so expensive at the time.
Likely, this guitar was commissioned rather than purchased over the counter.
Much like nowadays, you have to commission a GC-70 if you want one at $12,000 US.

From what I learn, the GC-7 took at least a year to make.
The finish was meticulously applied over a long period of time.
The original label was dated 1970.
The second signature looks like "Gotoh '72".
It looks like it was written on the label before it was assembled.
Perhaps, the original owner who commissioned the GC-7 requested
Gotoh tuner instead of the normal YTM-62 (I am guessing here)

Here are the specifications of the GC-7.

P.S. The back and side are also solid.
I just did not have it on my attachment.

Hi waikuentsui,

Based on my 1970 to 1974 "Yamaha Hand Crafted Classic Guitars"catalogue, the top model is the GC20D. I believe that Yamaha only started the "special order" some time after 1984 for the GC71 also knowrom then as the "Segovia or Custom". The GC70 was still available in the showroom. The the GC30A(1974 to 1984 top model) then was still available in the showroom as I saw one on display in the Yamaha shop in 1975. I think it was probably in the 1990's that Yamaha requires special order for their top model the GC70.

The GC71 had different bracing from the GC70. The GC71 produces a milder tone due to the reduced angle at the head and is supposed to produce greater bass response. The body shape is also different from the GC70. However, I think that the input by Segovia didn't help produce the desired result. The GC71 "Segovia/Custom model" was sold for awhile and probably didn't catch on and was dropped from the line.

Lim,

Thank you for the correction.
Like I said, I was guessing.

On the tuning machine, from 1974 to 1977, Yamaha GC30A uses the Yamaha tuning machine, however from 1978 onwards, they changed to the Gotoh tuning machine.

Hi. I've been trying to find some information regarding a beautiful Yamaha GC-7 I was recently lucky enough to pick up. As you will be able to see on the label there seem to two dates: 1970 and then also a signature with another date of 1972. If anyone out there has any info at all it would be greatly appreciated.
I know there were 2 specific Grand Concert models with the GC-D -series from 1970-78 & during this reign the GC-A came out - 1974-85! I wonder how many more. Your guitar is new to me and I do not see a series letter after the model number such as the D of the A. I am at a loss as Yamaha, as I understand it, would change their model numbers and cosmetic changes just to make a new line and more money.

I wish someone could give us a full rendition of all Grand Concert models produced during the 70s and into the 80's.

If Mr Waikuentsui could see this link and add his knowledge if possible, he would be interested in this guitar for sure. It is odd that there is no model number etc. I will see if I can get him to put his two cents in.

My apologies, I got a notice of activity and I jumped in thinking this was a new or newer post, now I see that the question has been answered previously, but I still wish we could get a clear understanding of Yamaha's number of GC models during this 70-mid 80 as well as the CG models as well. Yamaha really did not seem to play by normal rules!

I used to have a GC3a, which I picked up for £40. It was a bit battered and the bridge was lifting. I glued the bridge down and sold it for £200, which was still a bargain. I always regretted selling it, so when I recently saw one on the bay for £200, I couldn't resist! Its in much better condition than the one I had before too!

Hi and thanks for all these wonderful posts! I have attached images of my dad's GC-10. Is this the luthier of which you all speak: Toshio Kato?

Also I am curious being a novice what is the difference between the GC-10 & the GC-10A and why on earth is there so little information out there on the GC-10!??

Thanks,

Mike

CHS,

Your GC-10 was made/signed by Kato in early 80's.
Models GC-10, GC-10M and GC-10S were intended for local consumption in Japan. You will not find much information on them outside Japan.

Models GC-10A, GC-10C, GC-10D were exported to the outside world. You will find more information and availability.

Here's my 1977 Yamaha GC-10M by Toshiro Kato
It's in beautiful condition with origin Hardcase and user manual!
it was refret by a local luthier few weeks ago and just get it back.
the origin fingerboard is black, but my luthier polished the fingerboard in order to refret it,
And I keep the beautiful ebony striping instead of black fingerboard stain.

I saw this on an ad for a Yamaha GC20A on sale at the Fellowship of Acoustics site in the Netherlands. I've included the details below as they include a little bit I didn't know before and I thought it might fill in a gap in the knowledge of others here.
I only looked at it in the first place as I still have a GC20AC (Cedar top) from 1979 and wondered how similar it was.

Yamaha GC20a Grand Concert Quality 1a Classical Guitar, EC+

Top of the line Yamaha GC20a made in 1983 in excellent+ condition with only a few tiny dings to the table. Actually the condition is quite amazing for a 30+ year old guitar. The A series of Yamaha Grand Concert models (GC3a,5a,7a,10a,15a & GC20a) were made from 1979 to 1985. They are unique among the GC models because they have the smallest body size of all the series. They are closer in size to a Granada school guitar, which is interesting because during the 1960s, Yamaha paid Granada guitarmaker Eduardo Ferrer an enormous amount of money to teach the Yamaha guitarmakers how to make classical guitars. This instrument features Brazilian Rosewood back and sides, a German spruce top, mahogany neck, ebony fretboard and rosewood bridge. Includes original hard shell case.
Model Features:
Model Grand Concert
Body Material Rosewood
Top Material Spruce
Finish Natural
Neck Material Mahogany
Neck Profile Classical Flat
Fretboard Ebony
Bridge Rosewood
Scale 650mm
Nut Width 53mm
Tuners Strip tuners
Pickup /
Travels in Hard Shell Case

I search GC10C, GC10S and GC10M on Yamaha Guitarchive website(https://www.yamaha.com/apps/guitararchi ... 2.asp?t=ac)

it shows that three model's Back / Sides are:
GC10C : Solid Rosewood
GC10S : Solid Indian Rosewood
GC10M : Indian Rosewood

I considered this three guitars the same series with different top,
but GC10M did not show "solid", I wonder if GC10M's back/sides is made by laminate wood? or it's just a mistake of the database?
Is any one have any clues?

Hi everyone, am new in the forum. Am also a big fan of old GCs. I read at one point some GCs used brazilian/jacaranda back and sides. The picture below of an old GC-- if it is not indian rw-- then what could be it? Thanks in advance.
