ZB-12F Unslotted Replacement Nut for Guitars (Common on Fender)

What sorcery is this ?

Jun 3, 2018

Just put one of these on an old beater of a cheap strat-clone kit that I use to experiment with "creative" wiring. Suddenly its in tune up and down the neck and stays that way after using the trem as well. It cost half the price of the kit but it has significantly improved the value of the instrument to me. It required a little sanding of the back of the nut but nothing drastic. I dont have many dedicated luthier tools so the fret wire is not trimmed perfectly (but the look is in keeping with the overall "relic'd" appearance of the guitar). The question now becomes can I get a discount if I order these in bulk?

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.

Great Idea And Product

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

Pretty easy to install - sand it down to fit - pick the fret that matches the rest of your fretboard - couldn't be easier!
