Fixed my problem perfectly!!

I was having a very hard time finding the right nut replacement for my mandolin. Finally found this one at StewMac. Have never used the zero glide before, but this one works great. Had a good deal of sanding to do for a perfect fit, but it works great and sound is super on my mando. Thanks guys!!

Installed in a vintage Japanese Custom Shop Fender Tele. Great low action and better tuning stability. Easy install as well. Thanks for a great product.

Now that I have it setup I love it. The kits should have all available nut wires in it. I had to special order the largest wire for my Martin Dred kit because the included were too small.

Low Action, High Satisfaction!

My old nut was too high. And I didn't want to buy 6 nut files. This Zero glide was much, MUCH cheaper, and it was an easy instal. I taped some 400 grit sandpaper to a plank I had laying around. Sand sand sand, check the fit, repeat. I tried each fret it came with and chose the jumbo. I consider this a major upgrade to my home built super strat.

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.
