GOTOH® UPT Planetary Ukulele

Gotoh's UPT planetary ukulele tuners were designed by Japarts' own Yusuke Kawakami to blend classic looks with modern functionality. They come in three body finish options, nine standard button options, and three Japarts-exclusive button options, giving you a total of 36 great styles to choose from!

Important Information / F.A.Q.

Regarding string post length:
There is an optional longer string post (UPTL) for headstocks with a thickness of 12mm (0.472") or more. There is no difference in price. Please measure your ukulele carefully before ordering.
Will these fit my ukulele?
If you are replacing friction pegs you will almost certainly need to have the peg holes re-bored. We recommend that this be done by a professional. The diameter should be 9.7-10mm or just a bit wider than 3/8". With regard to headstock thickness (see above) you'll need to measure your headstock.
Do I need to tighten the screws like friction pegs?
Yes and no. Let's start with the no: You probably won't need to make any kind of adjustment. But on the off-chance that you do (you'll know - the post would un-wind from string tension) it's easy to tighten to the right amount of tension. Which brings us to the yes: Technically, the planetary gear is engaged by the screw that holds the button in place. Unlike friction pegs, there is a very wide range of "works well".

Tuning a ukulele with UPT planetary tuners is a pleasant experience. It may take you some time to get used to that.
Why are some buttons more expensive than others?
There are two main types of plastic buttons: molded ABS and carved acrylic. The molded ABS buttons (UBB, UBN, UB4B, UB4N) are solid colors without any variation. The acrylic buttons (JP1, JP2, UB5B, UB7, UB8) are carved from blocks of patterned material so that they can have a natural look, eg. ivoroid, pearloid, tortoise shell. The appearance, process, and material of the acrylic buttons adds to their cost.
