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

"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."
