Currently, I own a 1980 Yamaha GC30A and a 2006 Yamaha GC70. I am at the moment in the process of buying a 1974 Yamaha GC30A. Am I crazy?
It would be interesting to compare the sound of 30A made in Japan and 30A Taiwan ..

I'm not sure that the GC30A was ever made outside of Japan?

Yamaha has never made their top model outside of Japan.

Taiwan only produce the GC30. I have compared the GC30A and the Taiwan made GC30. They are world's apart.

You're right.
It is obvious that GC30 will have the quality of the lower sound, at this point it would be fair to compare GC20A, where I think the difference will be minimal and the price difference will be justified only by the japonese labor..

You could post bracing of your 30A?

I'M thinkin about ordering in a near futur a Yamaha GC 82C (probably next summer)

I was wondering if they will update the model soon.
I would love a 12 holes bridge and maybe an armrest.

It's not a deal breaker as I could add those after I bought the guitar.

Also on the yamaha canadian web site if you look at the GC82C you can see that it has the old fashion headstock wich I love, is it an option?
Have you decided?

This is the original tuning machine for the 1974 to 1978 Yamaha GC30A and the Yamaha GC20M which uses the same 39mm spacing rollers. I have yet to acquire a pre-1978 Yamaha GC30A. However I managed to buy the treble side of the original tuning machine from Japan.

So, my next best option is to reproduce this tuning machine and wait for a pre-1978 Yamaha GC30A to appear in the resale market. I got Rodgers to make a reproduction for me using the best materials that he can get for me. This is definitely the most expensive tuning machine I have own.

Those are gorgeous tuners! With the slightly higher gear ratio (15:1 versus 14:1) and bearing rollers, the tuning action must be silky smooth.

I just love the shape of the Yamaha tuning machine. I am just toying with the idea of asking Rodgers to reproduce one with a 35mm spacing for my Yamaha GC70. I am not sure if it will look nice with a 35mm spacing.

As long as the overall length of the tuner plate is the same, I would think it would look just fine...?

+1.
I doubt you'd notice the difference once they were fitted on the guitar.

My 20A has cedar, just to be different. I keep saying to myself “I should sell it” but I never have. One day maybe.
