    Lightbulb Gotoh UPT Tuner

    I like friction tuners on my ukuleles especially soprano. But I sometimes frustrate to tune strings with electric tuners, because they are too accurate. Gotoh UPT tuner looks same as friction tuner but it is planetary tuner, which has 1:4 gears inside. Very easy to tune and stay long as geared tuners.

    We just need three items.
    1) UPT tuners: Gotoh has two planetary tuners, UPT and UPTL. The UPT manufacturer recommended head thickness is 10-12 mm. UPTL is 11.5-13.5 mm. If you have 12 mm thickness, both works, but UPT is better than UPTL. Because we don't need extra length of tuner pole.
    2) Taper pin reamer: I use 3-15mm one. Any taper pin reamers around this size are ok.
    3) Drill



    Instractions
    1) Remove the friction tuners.
    2) Expand the holes around 10mm with reamer both side of headstock (see the left figure above) . Headstock wood is very light and very easy to cut.
    3) Drill a small hole next to the tuner hole (see the right figure above). The location of the small hole is easy to identify by UPT's thorn, which prevent to turn the tuner on the headstock.
    4) Set up tuners.

    I have installed 5 sets of UPT tuners for me and my friends. Very good tuner and install is quite simple.

    Thanks, great instructions. I'm way too scared of doing damage, but luckily, the guys at HMS will change friction tuners to Gotoh UPT for a small upcharge. They also made an instructive video of how to do it:

    Excellent instructions, the pictures you always include in your posts are extremely helpful, thank you. I have a Mya Moe baritone with "rabbit ears" and I didn't like the look. I switched them out for my favorite, black on black Gotoh UPT. The existing holes were just a little too big, alway check first. One single wrap of electrical tape around the barrel of the tuner made it a perfect fit.

    Hi Dave, can you share a picture of what the back of the headstock looks like? Can you see the old screw holes from the geared rabbit ear tuners that you removed? Thanks!

    Here is the back of the headstock. I left the holes unfilled, I NEVER look back there. I did a similar switch over on a Pono tenor and spent the time filling and stain matching. Then never looked back there so I left the MM as is.

    I have always used a thin brass shim to take up any size difference. In the banjo world we would find this when fitting a ⅜" planetary (such as Gotoh, Five STAR or Waverly) in a hole for a 10mm tuner such as a Schaller. I hate black tape!

    Well the black tape is wrapped around the barrel of the tuner which is then inserted into the hole in the headstock. You dont see it. So.........!!!!

    I love the Gotoh UPT-L tuners. I've installed a few myself.

    Nice replacement for nearly any other tuners.

    Thanks! Did you have to wait two months to get the tuners? I ordered them, but I have to wait.
