ZS-20 Slotted Replacement Nut for 12-string Guitars

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 just put the Zero Glide on my guitar. Very impressed. This is as close to perfect as I can get. I can bend all over the guitar and 95 of the time the notes come back to the original pitch....the few times they don t it s so minimal most people wouldn t notice it....I really believe that it s probably the tuners....they re decent low grade tuners. Nothing special. Amazing considering this is a 300.00 guitar. I checked the space between the 1st fret and the E and B strings fretted at the third fret...distance between 1st fret and bottom of string .....they looked like they were less than a thousandth and the guitar was not buzzing on an open string. The action is very low with extra thin strings on it. This made the guitar play even easier. I had the strings set at about 4 thousandths from the first fret while fretting at the third. This took them lower....especially on the first 5 frets. Good job on this I do wish they would have sent me a smaller fret.
