This is how my Yamaha GC70 look like with the tuning machine removed from the headstock.

Can’t recall the outside but what is shown here looks very much like Landsdorfer/Reischel tuners! :wink:

this is the case that came with the gc22
The case that came with my GC42 is exactly the same as that.
That's the one. That's what I was hoping to find.


It's much more substantial that the padded gig bags that I've seen otherwise.

I recently came accross a 1972 GC6D, its in beautiful condition, and only needed the usual setup work, to get the guitar where I like it. Over the years, I have had quite a few guitars in my hands, some were very impressive, some not so much, some were very expensive, but not so good, others really surprised me. The 6d has replaced my go to guitar as my main instrument, and at this point, I really don't want to play anything else! I have done some research on the 6D, I know what it is, and where it sat in the lineup, what its worth, etc, etc. I'm wondering if anyone else has had the same experience with one of these that I had, mine is among the nicest guitars I have played, which really surprised me. :)

I need to replace the tuning machines on the headstock. I would like to replace them with as close to the same tuning machines as was used on the original guitar. (Right-hand set is original, left-hand set is not.) The spacing between tuning pegs is 39mm. 99% of tuning pegs made since the mid-1970s use the standard 35mm spacing, and will not fit this guitar. I have only been able to find one set of tuning machines from Gotoh with the 39mm spacing. While functional, they are not at all similar to the original tuning machines.

Anyone have any leads on where I can get a replica of the original tuners? I have already contacted Rubner who will create a custom-made replica...for a third of what I paid for the guitar. :shock:

SHARING: In researching my guitar, I came on the Yamaha Parts List System. The link below takes you to a complete list of Yamaha Grand Concert models produce along with the years they were produced. Clicking on the model number link will take you to the specific page listing all currently available replacement parts. Sadly, few parts are available for the oldest models.

I wish the Yamaha GC archive were still up...

This all depends on your requirements. Their cheapest Landsdorfer style tuners are about 30€ and the costs should not more than double to have them customized to 39 mm spacing. No engraving, no shafts, no teflon bearing or other thrills but the gear will be identical to the most luxurious designs. There will be noch cheaper source for custom-made tuners than Rubner.

The only other alternatives to Gotoh 40G2000 lyra style tuners are individual tuners!

These are the Lyra type Gotoh 40G2000 tuners! The only 1:1 replacement in the market for old Kohno and Sakrai tuners with 39 mm spacing! :wink:

There is approximately 0.2mm difference between the first and last screw holes for the old Gotoh and the current . 1-17/33 inches verses 39mm. It is still within tolerance.

Well noted. Boreholes in wood are never so precise as in metal for instance. These replacment tuners fitted my ´78 Kohno 30 perfectly with negligible offset of the fixation holes. But they are only available with a Lyra style plate, which is not the style Yamaha used and uses for the GC line. :?
