Zero Glide ZS-19 Acoustic Guitar Nut for Ukuleles

The nut did not need any sanding. It fit my old Hola concert ukulele. I didn't want to risk my more expensive ukes. It does leave a small gap behind the nut due to being thinner than the original. I did have to sand the g-string slot due to my wound low-G string. I don't plan to do it again. The overall improvement is minimal, but I'm glad I did it, once.

I'm a guitar man, and I've installed 4 or 5 zero glide on my guitars. A uke shoulda been a piece of cake, right? Not so! The description said, 'Acoustic Guitar Nut for Ukuleles'. So I figured I could sand it to fit. It might work for an alto uke, but it's no good for a baritone uke. It's too short! I should have checked my measurements closer, so my bad! I put the old nut back on.

The zero fret idea is great, I have an ukulele that came with it, so I was excited about installing this product on another of my ukuleles. However the nut provided with the installation kit is 1/8" thinner than the standard ukulele nut provided with most all ukuleles manufactured todaty. So when you remove your stock nut to install the one provided it does not install, that is it does not fit or fill the "stock" position. There is a 1/8th inch gap left in the headstock due to the thinner "nut" provided. It probably will not affect intonation but it sure leaves an ugly gap to try and fill in and finish. So beware that you've got some fine finishing work to do if you buy and install the Zero Glide unit made for ukuleles. I did not complete the install due to this problem.
