Julian: Are both 650 scale? - The Kohno looks better in my option, but that's just a matter of taste I guess.

I am new and am not sure this is the appropriate place, but does anyone know if this is actually Toshio Kato's signature?

Not yet. I'm contemplating a purchase but someone put steel strings on it.

The Yamaha GC71 is 650mm and Kohno No.50 is 660mm scale.

In this case the tone of Yamaha GC 71 is clean and precise like John Williams Fleta spruce 1961 whereas Kohno No.50 has a sweeter tone with beautiful overtones.

Anybody knows what is the tuning machine for Yamaha GC71 (1980's)?

Is that Karl Hofner (for Yamaha GC70) or Reischl?

The worm and gear including the shape of MOP button of tuning machine attached to my Yamaha GC71 look like the same with Reischl.

Any information?

thanks.

Knowing the Japanese culture especially the immediate post war generation, they are pro-Japanese. Chances are they are custom build by Gotoh for Yamaha. Even their latest GC82 range used Gotoh Premium.

No doubt Yamaha including Masaki Sakurai use Gotoh tuners thesedays. But in the past Kohno used Rodgers tuners and Yamaha used Karl Hofner tuner for the Yamaha GC30a guitars which are equivalent with the GC70s. For the GC71 model, Yamaha didn't inform the brand of tuning machine mounted on the guitar.

The GC 71 is a derivative of Hauser 1 and Santos Hernandez. The headshape has three lobes the same with Hauser. And Hauser installed Landstorfer (subsequently Reischl). So my GC 71 has a tuning machine similar to Landstorfer with three lobe headshape.

My Oskar Graf has a Reischl tuning machine. When I compare the two, the tuning machine of GC71 resembles Reischl except its side plate has an engraved motive. The worm, gear, sleeve, MOP button shape is identical with Reischl. So I would assume Yamaha in 1984 used Reischl for the GC 71.

The purpose for me to inquire is that I plan to replace the existing tuning machine with a Reischl which is now not available in the market. Reischl retired a few years back. I asked Fritz Ober to locate a Reischl tuning machine for me.

It may be good to ask Akio Naniki directly, but I just don't know where to contact Mr. Naniki.

My experience with my 1978 GC30A is different. When I first acquired the guitar, the 6th string winder wasn't working and it uses a 39mm spacing tunning machine. I managed to find a 39mm spacing Gotoh. It fits perfectly including the screw holes. The main difference is the motif on the plates are different and the Yamaha one has a "butterfly" button. Everything else is similar.

Hi there, another Yamaha GC owner and fan here!

Country/City: Arizona, USA
Model: GC6D
Date of production: 1972
Date of aquisition: 2015
Price of aquisition:
Top: Solid Ezo Spruce
Back: Solid EIR
Sides: Solid EIR
Neck: Mahagony
Fingerboard: Ebony
Construction: Spanish heel - Granada style
Scale Length: 662mm
Luthier Signature : Kato
Strings: Hannabach 800 SLT

It's a very nice sounding and versatile guitar. I enjoy playing mainly modern and baroque music on it and I'm slowly getting used to the longer scale. I mainly play at 630mm. It is not the loudest guitar, but it has a wide range of usable tone color and dynamics.
2017 Benito Huipe "Bouchet" Spruce 655mm
2015 Francisco Navarro Concert Cedar 630mm
1977 Yamaha GC-5S Cedar 658mm
1972 Yamaha GC-6D Ezo Spruce 662mm
