ZB-9 Unslotted Replacement Nut for Banjos, Mandolins and Ukuleles

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.

I nutted

I bought one for my generic mass produced bass don't get me wrong It's an awesome bass . I recently had It refretted with jumbo gold bell brass frets and It's regular plastic nut started to feel off. I did a little search on web and came upto this products. I combined It with my leftover gold fret wire and boom I Nutted Finally after years of trying to prevent using open strings on my bass I can enjoy that low open string notes sustaining to eternity. 100 recommended and If you ever get a custom made instrument insist on the 0 fret option. You can try different gauge strings without worrying about nut slot shapes and widths.

This Fixed It

The G string on my Epiphone Dot was bound up in the nut and always pinging loose when trying to tune it. It would suddenly be sharp then suddenly flat etc. I installed a Zero Glide on her her and problem solved. Not only that but it has also improved tone. Honestly I was just trying to do a quick fix in order to sell her but the new life in her changed my mind.
