Had tuning stability and buzzing issues after ten years on my first bone nut. Also have always been bothered by open string vs. fretted string sounds. I play mostly flat picking/crosspicking styles and Travis style picking. The consistency of the note makes both more enjoyable for me. No buzzing lower action smoother tuning smoother playing easier bending etc... Have all been a result. Took me about two hours to get height and width of nut and fret correct. Had to get a smaller get shipped from gold tone and their customer service was the easiest I have ever experienced. Had part in two days and I am satisfied.

Zero Glide Query

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.

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.

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

Just got a second one. Used the first on a Tele build. The multiple heights included give plenty of options. Takes some tweaking but so does a standard nut and you don't have to worry about overdoing anything.
