ZS-1 Slotted Replacement Nut for Guitars (Common on Gibson)

An Excellent Product!

Apr 30, 2016

I bought two of these, one Gibson-style and one Fender-style for two of my favorite project guitars, an Epiphone LPX and my Jazz-O-Caster parts guitar. The Gibson was a near drop-in, needing only some trimming and shaping for a perfect fit. The Fender was slightly more challenging, as the neck on the Jazz-O-Caster never saw the inside of any Fender-approved factory! It required a 1/32" shim underneath for a proper fit, and some sanding to make room for the tang. There was a marked increase in the brightness of tone for both instruments, as well as improved intonation. This is MUCH easier than installing a traditional nut, and nearly foolproof IF you follow the instructions. Thanks, Stewart-Macdonald, for stocking such a well-engineered product.

Unslotted 12 string ZerO Glide

Oct 28, 2017

I recently custom installed a ZerO Glide on my 40 year old 12 string guitar and it really has done the business. There has been a marked improvement in volume and sustain tuning is much smoother and the intonation is spot on.

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.
