Zero Glide Query

Jun 23, 2025
I have a BC-350 banjo with the zero glide nut. It has been problem-free but I'm curious how this is an improvement over the zero nut found on budget European guitars since practically the beginning of time. I repaired instruments for decades and always regarded the zero fret as a marker of an inferior mass-produced instrument. No criticism of the Gold Tone zero glide is in any way implied here but I am confused.

Unslotted 12 string ZerO Glide

I recently custom installed a ZerO Glide on my 40 year old 12 string guitar and it really has done the business. There has been a marked improvement in volume and sustain tuning is much smoother and the intonation is spot on.

Great Product For Any Guitar.

Wow, what an innovation! This product eliminates the critical process of nut filing completely disappear to be replaced by a zero fret which enhances the sound of your guitar. It is not without some challenges in installation, but once completed your guitar just sounds and plays better.

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,
