3rd Zero Glide for me

Nov 3, 2023
I've had 3 Zero Glides installed for me on a couple of banjos had a luthier mess up one of them unfortunately and eventually had to get a new one installed by another luthier. To me the sound on the open strings is clearer and cleaner sounding than with a plain bone nut. And the strings never bind in the nut slots when I'm tuning them.

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.

This is one of those things that you ask yourself why has no one thought of this before, but it likely would have been very difficult to produce on a volume scale without CNC machines.......I put the ZB4 on a Washburn parlor guitar and was amazed at the difference in tone clarity, sustain and definition as well as tuning stability and the lowest possible action.........What more could you ask for for one single mod??.....Zero Glide makes several different sizes etc to fit just about any guitar, so be sure you get the right model for your instrument. The unslotted ZB4 requires slotting, so it does require some skill and proper files. I would recommend letting a tech install if you have no experience or tools. I do predict that some of the major instrument makers will be using this in the near future. Why did'nt I think of this. JB/Texas

Bought 2

One for Fender Telecaster, the other for Breedlove acoustic. Both of these guitars are top 10 instruments. The Zero Glide nut improvement came through as described on Youtube demos. So much better string action (lower with out any fret buzz) Clarity in open string tone chords and pulloff plucking, faster tuning to pitch, using electronic tuner, remaining in pitch once strings stretch has settled in. I took my time to install on both guitars about 2 hours for each instrument. Have new custom Guitar that I will 99% sure I will add this improvement to soon. I see this becoming a standard upgrade to many popular manufactures. Lastly the sustain in open chords on all strings cant be described.
