ZS-15 Slotted Replacement Nut for Guitars

Just put one of these on an old beater of a cheap strat-clone kit that I use to experiment with "creative" wiring. Suddenly its in tune up and down the neck and stays that way after using the trem as well. It cost half the price of the kit but it has significantly improved the value of the instrument to me. It required a little sanding of the back of the nut but nothing drastic. I dont have many dedicated luthier tools so the fret wire is not trimmed perfectly (but the look is in keeping with the overall "relic'd" appearance of the guitar). The question now becomes can I get a discount if I order these in bulk?

An inexperienced guitar tech worked on the nut of my Guild M75 Aristocrat electric and I ended up with a "sitar" sound on my high E string and a dead G string and bad intonation. A friend recommended Zero Glide and that company recommended this particular nut.

Installation was not particularly difficult for a handy guy, but took two hours and involved sanding nearly 1/8 inch off the bottom of the new nut and 1/16th plus off each side while being careful to keep it even. The video on the company website helps. Once fitted correctly you decide how big of a 'zero fret' you want. There are four of different sizes in the package. I tried them all and found that the smaller ones provide very low action at the nut (which is nice), but require a higher action up the neck to clear the first fret where the strings can rattle. I ended up using the largest fret provided as it allowed me low action where I need it. Once you have it figured out you trim the zero fret to length and glue it
