I am late with this info and I am sorry. You wrote.....
""I was hoping the strings would slide smoothly over the tusq nut but one or two of the bass strings still hang up during tuning (mostly the D string). Any suggestions as to how I might file the nut a little to keep that from happening?""

I always rub the nut slots with a pencil whenever I change the strings. I use the 2B (softness or hardness ??) .5mm leads in my Pilot pencil.

Yes... you file very lightly to the edge that is catching to produce a round or radius. Fine emery paper will work fine. A similar process is used to remove the sharp edge on the underside of the fingernail after shaping. Alternately, you can gently lift the string as it is being tightened a few times. In this manner the wire wraps clear the sharp edge until you reach tuning tension. I would recommend the first solution.

The first Janpanese luthier at Yamaha trained by Ferrer is Ezaki(江崎). That's is what the signature " 江崎秀行" on the label.

On a second technical point, I notice that today, all green aberrations have disappeared from my posted images? I also realized that the two posted images appear the same size in the posts despite the fact that the second upload file was 2.5+ times larger than the first. Perhaps an administrator will have the answer to this mystery.

Finally...to provide a more readable image of the writing on the label:
Japanese Luthier's Name.jpg
It is japanese, the luthier is H.Ezaki (江崎秀行).

Iam looking at a 1986 GC31 with Kato signature, in my research i found that he was the first trained, so i don't know who it was really.

Hi and thanks if anybody knows how I might date this guitar. The salesman called Yamaha but no luck. I liked it so much that I didn't care and bought anyway but I am wondering. They had us look inside for any other number but nothing can be found. Thanks again for your time and knowledge.

Hello Susan. I have a much-loved GC-3 from 1987. I know that the GC 3 up to GC70 were made in the 1980's. The style of label in the photo is the same as mine.

A quick search of Yamaha Guitarchive will give results for GC10A, but not GC10. This leads me to believe that your guitar is from the early part of that series, say 1979, or perhaps even prior to that.

In any event, you have a very worthwhile instrument. Try different strings to bring out the best sound.

Cheers,
Cary

Hello Susan,
Your guitar is made from Kaohsiung, Taiwan.
I had met yamaha former staffs in Kaohsiung factory recently and knew some information about.
Your guitar is made at the end of 70's latter or early 80's, Japan and Taiwan factory made GC-10 concurrently then.
However, Kaohsiung factory change their model name later.
Japan produced hign end model and leave the middle and lower model to Taiwan factory afterwards.
That's the story.

Thank you very much Marxtom. I so appreciate the response. This guitar appears brand new and the action and neck are perfect. I can't imagine someone would own this guitar and not play it. Great quality and sound and I am already enjoying playing it. Thanks again! Susan

I bought a gc3a off the big auction site. I had to reglue the bridge and there is a fair amount of superficial damage (which adds to the guitar's character IMO) but it plays and sounds great. I defy anyone to find a better guitar for the price I paid (about 100GBP inc postage and cost of bridge repair).

I played with your image a bit with only iPhoto for the Mac. I can certainly see it is a 1971 CG 10D with a signature that appears familiar, but don't they all when you don't know the language!

Have you tried lightly cleaning the surface of the guitar, there may be leftover cleaners or something on the surface? I got rid of some of it by playing with tint etc, but did not help too much.

My above post was not meant for this forum and the post was done by mistake. I was reviewing a GC 10D at the time and must have got confused which forum I was on. These post, although, look wonderful and may be very useful to me tracking down a real Kato Toshio signature (in Japanese). My daughter took Japanese studies at university and she said she thinks she may be able to help. In 2001 I emailed the Japanese manufacturing plant and sent photos of my guitar. I was advised that Kato Toshio was the luthier and that it was a high end handmade model and in 2001 USD if it were then made and on the market it would be approximately the equivalent of a $5,000 guitar. This information verifies that my Kato signature is legitimate, yet there are many CG 20D guitars out there indicating that they are signed by Kato in Japanese but do not match mine. I would be interested in any information and will read this thread from the start with great interest.

I am interested in buying the History of Yamaha Guitars, ISBN 0634053264 if my 1972 Yamaha guitar GC-20 is included along with the rest of the line at that time from the GC-3D up to the top GC-20D. I have the catalog listing of 5 guitars, 3, 6, 10,15 and the 20D? I would like a little more that just a photo rather a bit of a story on the line. These were all hand made made in the Japan factory with remarkable inlays,

Thanks
