Get Rid Of The Gibson *Tink*

Mar 15, 2016

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,

This Fixed It

Nov 3, 2023
The G string on my Epiphone Dot was bound up in the nut and always pinging loose when trying to tune it. It would suddenly be sharp then suddenly flat etc. I installed a Zero Glide on her her and problem solved. Not only that but it has also improved tone. Honestly I was just trying to do a quick fix in order to sell her but the new life in her changed my mind.

Worth The Effort

May 15, 2016

An inexperienced guitar tech worked on the nut of my Guild M75 Aristocrat electric and I ended up with a "sitar" sound on my high E string and a dead G string and bad intonation. A friend recommended Zero Glide and that company recommended this particular nut.

Installation was not particularly difficult for a handy guy, but took two hours and involved sanding nearly 1/8 inch off the bottom of the new nut and 1/16th plus off each side while being careful to keep it even. The video on the company website helps. Once fitted correctly you decide how big of a 'zero fret' you want. There are four of different sizes in the package. I tried them all and found that the smaller ones provide very low action at the nut (which is nice), but require a higher action up the neck to clear the first fret where the strings can rattle. I ended up using the largest fret provided as it allowed me low action where I need it. Once you have it figured out you trim the zero fret to length and glue it

Acoustic Glide Nut

Oct 7, 2016

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.

Single best upgrade I ve ever done

Jan 11, 2025
Replaced a stock plastic nut on my Squier Jaguar short scale bass with a zero glide today. Hand down the best upgrade I ve done to that or any instrument since I ve started playing. Action is now perfect intonation is spot on tuning is even better/easier as there is less friction to deal with. My initial reasoning for this upgrade was to minimize any nut work needed when changing string gauges now I just have to set intonation and tuning and it s good to go I didn t expect the immense open string clarity change nor did I expect that this bass could get any more sustain out of it but I stand corrected I ll be upgrading every bass and guitar I own to a zero glide now If you re on the fence just go for it - you won t be disappointed
