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,
My circa 1997 American Standard Strat always had a problem with staying in tune after whammy bar use. I tried pencil graphite and different string sizes with not much luck. I put this nut on and a set of Gotoh locking tuners and now it seems to stay in tune very well.
Just put one of these on an old beater of a cheap strat-clone kit that I use to experiment with "creative" wiring. Suddenly its in tune up and down the neck and stays that way after using the trem as well. It cost half the price of the kit but it has significantly improved the value of the instrument to me. It required a little sanding of the back of the nut but nothing drastic. I dont have many dedicated luthier tools so the fret wire is not trimmed perfectly (but the look is in keeping with the overall "relic'd" appearance of the guitar). The question now becomes can I get a discount if I order these in bulk?
I installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.
