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

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.

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

Easy install with fantastic results

Sep 16, 2020

I have a Yamaha F310 and the nut was cut real high. Looking around on the internet I came across the ZerO Glide and decided to give it a try. It was less expensive that having the nut cut or purchasing the tools to do it. Printed out the sizing chart and found the ZS-5 had the correct spacing. In less than an hour my guitar felt and sounded great. This is one hell of a product and glad I made the purchase.

Great Tone

This was my first attempt at installing a zero glide. It only took me about an hour to complete the install and I am very pleased with the tone of my open back banjo with the new zero glide nut!
