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.

Zero Glide ZS-17F

I purchased a '97 Squier Vista MusicMaster Bass locally. The stock plastic nut needed replacing or filing. I had already pulled the nut off of the MusicMaster and had all measurements noted before replacing the stock nut temporarily. The Zero Glide ZS-17F Precision Bass Precision Bass model specs matched up with the MusicMaster specs. Cool. After my Zero Glide arrived I pulled the stock nut and lightly sanded the nut slot on the fretboard with fine sandpaper to remove any debris or adhesive residue used on the stock nut. Next I slid the Zero Glide nut onto the fretboard. Nice snug fit. The width of the Zero Glide was perfect. My next step was to make sure that the top / flat surface of the nut was flush with the fretboard. This is crucial to allowing the fret to seat correctly on both the fretboard and the zero fret nut. On my MusicMaster this required a very thin shim under the Zero Glide nut. Once the nut was seated properly it was just a matter of selecting which of the fret sizes provided is required for the instrument. In my case this was the longest installation step time-wise. Once you have selected the proper fret, mark the fret and cut with the proper tool. Examine the cut end of the and correct any imperfections due to cutting on the tang of the fret by filing. A small bench top vise with padded jaws and high quality file makes this step a snap. Installation time in my case : - shimming me the nut, less than 10 minutes - selecting the correct fret size, 45 minutes - all filing on the fret ends and top corners of the nut, less than 15 minutes I'm very pleased with the results. The open string notes sound like fretted notes of course, and I was able to achieve noticeably lower action without fret buzz after a setup. I'm especially pleased with the improved note definition of the open E and A strings. I did not check the intonation with the stock nut on the 1st five or so frets before I installed the Zero Glide, but the intonation is fine on the lower frets. My order was processed and shipped promptly and Gold Tone customer service is excellent. Thanks for a great product !

I've got a '67 Gretsch Country Gentleman that has what they called the zero fret. I had always wondered why didn't anybody else do this. I put this on my 2010 Gibson Lucille and it solved the nut drag problem. I'm also going to put it on my '76 Les Paul Deluxe. A great solution to an on going problem.

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.

Wonderful addition to my old Yamaha FG-180 Red Label guitar

The installation was not difficult but it did require patience and good workmanship when shaping the Zero Glide. I bought the black version and really like it's understated appearance.
