The Zero Glide Replacement Nut System borrows the "zero fret" concept to reduce string contact in the nut by up to 93%, increasing tuning stability, playability, and open string tone. It only takes a few minutes to install with absolutely no permanent alteration to your instrument. For Resonator Guitars & Lap Steels.
I've got a '67 Gretsch Country Gentleman that has what they called the zero fret. I had always wondered why didn't anybody else do this. I put this on my 2010 Gibson Lucille and it solved the nut drag problem. I'm also going to put it on my '76 Les Paul Deluxe. A great solution to an on going problem.
I bought this for a Washburn Oscar Schmidt OE-40B archtop guitar, on which the nut had broken when putting on new strings. I always wanted to try a zero-fret nut and was pleasantly surprised at how well it works. Perfect string height and tone.
Great product, Makes a lot of difference in sound and play ability. To say nothing of staying in tune. I put one on a Ovation Legend made in 1972. The guitar always sounded good but was a little tough to play. This made a world of difference. It is now amazing. I have a friend who can't keep his hands off of it. He likes it better than his Rainsong.
