I hadn't see this thread before today. However, coincidentally, in the context of one or two other threads presently going on lamenting the sound of modern guitars ('Orpheo speaks with one voice' and 'Most Guitarists play with Soulless Guitars'), I was reflecting only yesterday that the Yamaha sound is right up there with the 70s Ramirez or Fleta sound that is so often revered.

Watching/listening to Brouwer play in the late 70s is wonderful both because of his playing and the tone/colour of his guitar.


I know Brouwer played with a Yamaha GC in the 1970s
This is from the 80s. Does anyone know if he is still playing that Yamaha here?

Based on the rosette design, the headstock and tuning machine, the guitars featured in this video is a Yamaha GC30A, probably the same guitar used in the 1970's.

Thank you Mr Lim.
I found a thread where it says that indeed Leo Brower used a GC30A (cedar). Two other professional guitarists in that list played Yamahas. Siegfried Behrend played a GC30B. And Liona Boyd a GC70C

I found this rather rare footage of Brouwer playing what the video title describes as a "rare color" guitar. Date unknown, could be early 70s but who knows.

Thanks for all the information you provide

It is very unlikely that the GC30A is cedar. If It is, Yamaha would probably name it GC30C or something to that effect.

No Fan!
My GC 30A C/BRW was build by T. Kato in 1980.
The woods and the craftsmanship appear outstanding except the "minor" fact that above the 12 fret the instrument was completely out of tune because the scale wasn't compensated.
After moving the bridge inlay by a fearless Luthier (now the scale is 1 - 2 mm longer) the guitar is overall in tune.
Someone with similar experiences...?

I don't understand what you mean by "moving the bridge inlay"?

...first the slot wherein the piece of ivory is placed has to be filled with a wooden replacement (glued in) then a new slot has to be cut into the bridge 1-2mm towards the holes.

Now get it. I am very surprise Yamaha can make such a mistake for their top model.

For what its worth I have a GC20A Cedar & Jacaranda from 1979 and on the label it says GC20A but has a C written in pen next to it.
The A and B are later versions of the 20, so probably the 30 et al too. First there was the 20 then it was altered or 'improved' somehow and that was the 20A then the 20B and I guess the C was after that.

Mine is very similar to the 'rare colour' guitar mentioned by Francisco above.
Getting better bit by bit, day by day.

Based on the "Yamaha Archive", the cedar top is not the GC30A but the GC30B.

Found this on the net.



[History of the Grand Concert Custom sound]
Basic form of what today is known as the classical guitar is in the 19 century Spain guitar production house Antonio de Torres ( ANTONIO DE TORRES:1817-1892 ) by was made.
Its style and technology handed to Spain affected his production house were, and then from Spain spread to the world.

4/1966, Yamaha will establish a guitar Research Division, started research and development of handcrafted guitars.

From October the same year next day ' craftsman tradition of Torres 67, Spain Eduardo Ferrer greeted us (Hamamatsu), Spain tradition of technology leadership.

By the hands of the craftsmen who learned this when ' was born in the 11/67 Grand Concert Guitar early model GC-5, GC-7, GC-10. This 3 model based on the orthodox sect Spain style gave great influence after Japan-made guitars.

It is this later as Spain Orthodox traditional manufacturing methods based on repeated trial manufacture and study, we had grabbed gradually sound relations, relationship between production processes and sound materials and structures and.

In 1972, Yamaha sent an engineer who in Spain.
He studied ethnic guitar craftsmen Eduardo Ferrer and Manuel Hernández, learned the production techniques over two and a half years in the culture of the home.

In addition ' in 1973, Hernandez, held technical leadership in Hamamatsu.

And sounds make this a new origin, we asked different types of tone, continued research and development. And guitars in 1974, custom guitars GC-a 30/30 / 30 C 3 type a personalities are announced.

GC-30A is a model combining methods learned Hernandez as the culmination of technologies accumulated in the GC series until it was developed as a premier Yamaha original sound.

GC-30B's model Hernandez manufacturing methods and ways of thinking, and pursued the sounds of Spain.

GC-30C is a model developed to help Spain craftsman soundboard sound, feel attracted to the sound of guitar time has elapsed.

These 3 types of sounds is further research and improvement, and has been handed down to was released in 1983, GC-50/60/70, GC-61, GC-62.
Also acclaimed musician prominent in the same 1983, Andres Segovia model GC-71 has been released.

Hi Jae Lee,

I noticed you own a Yamaha GC50C. Does your GC50C have this headstock?

Yes, exactly the same headstock. I've seen GC custom series 50/60/70/71, 61, 62, sometimes made by Kato, othertimes by Ezaki. I'm not sure which version is better. I'm not interested in GC series made after Kato and Ezaki retired. Early GC50 has solid Jacaranda, while later GC50 has solid honduran rosewood. Discontinued in 2012. Mine was was made in 1992 and has solid Jacaranda B &S with 650mm scale length. It's an extremely hard-to-find guitar. The best guitar I've ever played in my life. I sold all of my other guitars. You have GC30A, the top of the line at that time. You should be happy about it.

Yes! Indeed the Yamaha GC30A is awesome.

Yes, it is the same. The original tuning machine still works great. Is your GC30A made by Kato or Ezaki?
