Electric upright bass tuners?

[Jacob Wieder]

Hi, they look to me like they were designed for a nylonstring guitar.

i really don t know what an instrument like this is worth. I dont think you can make money here, but that is probably not the intention here? Because “all guitars should be saved” here are my two cents.

Double bass mechanis are normally not opposite of each other. They have a much longer shaft https://stoll-kontrabass.de/instrumente/kontrabass/kontrabass-florenz

My father and me have built an EUB maybe 15-20 years ago. I used standard electric mechanics and they couldn t hold the string tension. They actually broke.

I would remove the middle wooden part of your headstock, widen the holes and go for double bass tuners if that is possible. Attention: Double bass tuners have conicle shafts.

Rubner tuners are good, these are the ones i settled for with my EUB

cheapos are those:

Maybe you can cut those to length?

or maybe you can find someone who manufactures custom mechanics. Rubner in Germany does that, i think, maybe Schaller too. But of course expensive.

if you don t care maybe try modifying nylonstring guitar tuners.

Those look good, but for the life of me I can’t figure out how to interpret the language on that site…

Brands like eminence use standard fender bass style tuners and they hold tension of a upright bass string. Not sure if your peg head is big enough for that, but it’s worth a look if your customer wanted to replace all the tuner to be uniform.

Those are the same tuners on my old Japanese violin bass. I believe Allparts has replacements, otherwise they are not quite as hard to source as you may think.

They are basically a copy of the tuners Gibson used on slotted head bassesin thelate 60s and early 70s.

Thanks Ethan, I’ll give Allparts a try.

So these are the same tuning machine but with a different post. These came off a Japanese bass with a flat headstock, the post for a slotted head has a hole in the main diameter of the post, just like a tuning machine for a slotted guitar headstock (compare to the existing ones).

No luck on Allparts unfortunately.
