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

I m impressed with this. Easy to install. I m not a luthiar but I have refretted a few guitars and made some nuts and saddles. This is a pretty incredible system. I was going to cut a new nut for an acoustic guitar I just bought. I tested it and it was not sliding perfectly through the nut even though there was no ping while tuning. The way I test a nut is to strike a note then smack the string between the nut and the machine heads. behind the nut I put a tuner on the head stock so I can watch the note go up and come back. It simulates a good bend and you can watch the quality of the nut you have on the guitar. Most guitars will stick at about 6 to 10 cents above the tuned note unless you have a really well cut nut. At least the wound strings will....steel strings will usually drop back to the tuned note if the nut is decent . The nut I had on this guitar was pretty good....no pings while tuning yet it would still catch occasionally which effected tuning.

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.
