ZS-23 Slotted Replacement Nut for Guitars (Common on Gibson Z-Fan)

Great Idea And Product

Jul 6, 2015

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

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

YES there is a Zero Glide nut for a square neck resonator.

Do you play a square neck Dobro You know that resonator guitar that is used in bluegrass music Then get a Zero Glide for that instrument. YES it works. I have a Gold Tone OB150 5 string banjo where I was introduced to the ZERO GLIDE nut system. This started a long time love affair with this fine invention. I installed one on a mandolin my Martin D custom that is my number 1 guitar I have one on one of my Telecasters and the rest will soon get them. If it has a nut then it needs a ZERO GLIDE nut. This is very easy to install you can even do the sanding to fit it with a Stew Mac tool that you use to sand nuts and saddles so you will be sure to get a perfectly flat surface for best results. Follow the instructions and you will be able to install the ZERO GLIDE nut even if you are not an experienced Luthier. You can improve tone on a entry level square neck resonator guitar like my Morgan Monroe and any other fretted instrument you install the ZERO GLIDE nut system. You can replace the cone and the spider bridge and the saddles with all the Beard goodies you can get to make your Dobro shine tone wise but DO NOT FORGET the ZERO GLIDE nut system. The one mod that will save you from a world of pain. You will not have to buy a very expensive set of nut files to install and set up a ZERO GLIDE nut system because it is not required unless you get one without slots for a custom job. The nut is bone and the fret wire is metal sometimes stainless steel so you are actually adding to your tone and you take away the usual nut issues with a Zero Glide. Everything I put a ZERO GLIDE nut system on plays much better and sounds much better too. YES there is a ZERO GLIDE nut for your Dobro and just about everything else. Need something custom ZERO GLIDE can help with custom nuts.
