This is a full set of Gotoh UPT tuners - rear facing geared tuners with a 1:4 gear ratio.

There are different options of colour and size:

UPT Black and UPT Chrome - These require a hole 9.7-10mm long to fit. They are designed for headstocks that 10 - 12mm thick. Some minor adjustment may be required to the hole in your ukulele to fit.

UPTL Black and UPTL Chrome - These require a hole 9.7-10mm long to fit. They are designed for headstocks 11.5 - 13.5mm thick. Again some minor adjustment may be required.

These tuners have a screw on the end which can be used to tighten the mechanism.

Please note, while these are genuine Japanese parts, they are not sent in official packaging. I purchased some on behalf of a UK luthier and decided to get some myself too. I didn’t know they’d send them without packaging. I have packaged them separately with a small box.

To fit, you mount the tuner from the rear, then add the washer from the front, and screw in the bushing from the front. Very simple.

Please do measure carefully before ordring to make sure you get the right set for your ukulele.
