I put one on my Taylor 12 fret, it made a big improvement in string tone, tuning, and intonation. I'm now going to install them on all my guitars.

I've used this for over a month and I'm more happy now than when I first installed it. The intonation on my acoustic is better than it ever was...you can fine tune the saddle almost dead on for intonation. One suggestion.....be sure to glue in the zero fret with a few drops of glue once you get the guitar right. I was working on my guitar on and off for a month and didn't glue in the zero fret. I was taking the strings on and off. Every time you reinstall the zero fret it will be in a slightly different place. String against fret will cause a slightly different indentation in the zero fret. You want the string to stay in the same spot on the zero fret.

I just installed a Zero Glide Nut on my '14 Les Paul Studio. I was having trouble with the traditional *tink* and tuning issues often associated with Gibsons. Initially, I was going to try the new titanium nut made by Gibson but was told that it would not fit my '14 Les Paul. Keep in mind, I have never installed a nut before on a guitar where I needed to remove the old one. I had only fixed broken nuts in the past. I say this because I had a little anxiety when I decided to install the nut myself. The first thing I noticed was how much extra material must be sanded to get a perfect fit. For my application, I had to sand the bottom of the nut as well to get the fret to seat properly against the fret board. This may sound bad, but it is a good thing! It means that the folks at Stew-Mac realize (as I hope you do) that although these are precision instruments, there are many parts that are finished out by hand. The extra material allows for those minor variations and with a little work,

Works as described but installation was a pain. I have a warmoth tele neck that I installed it to. I had to cut back the nut slot a little to fit the new bone nut and fret in place. I thought it would just drop in.. I wasn't anticipating that but my skills didn't let me down. I filed the nut and fret down on both sides a little, added some super glue and now it works great. i have a bigsby so tunning is a breeze now!
