ZS-3 Slotted Replacement Nut for Guitars (Common on Martin)

Fixed my problem perfectly!!

Oct 18, 2020

I was having a very hard time finding the right nut replacement for my mandolin. Finally found this one at StewMac. Have never used the zero glide before, but this one works great. Had a good deal of sanding to do for a perfect fit, but it works great and sound is super on my mando. Thanks guys!!

Acoustic Glide Nut

Oct 7, 2016

I installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.

Wonderful addition to my old Yamaha FG-180 Red Label guitar

The installation was not difficult but it did require patience and good workmanship when shaping the Zero Glide. I bought the black version and really like it's understated appearance.

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.
