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.
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?
I have a Yamaha F310 and the nut was cut real high. Looking around on the internet I came across the ZerO Glide and decided to give it a try. It was less expensive that having the nut cut or purchasing the tools to do it. Printed out the sizing chart and found the ZS-5 had the correct spacing. In less than an hour my guitar felt and sounded great. This is one hell of a product and glad I made the purchase.
Had tuning stability and buzzing issues after ten years on my first bone nut. Also have always been bothered by open string vs. fretted string sounds. I play mostly flat picking/crosspicking styles and Travis style picking. The consistency of the note makes both more enjoyable for me. No buzzing lower action smoother tuning smoother playing easier bending etc... Have all been a result. Took me about two hours to get height and width of nut and fret correct. Had to get a smaller get shipped from gold tone and their customer service was the easiest I have ever experienced. Had part in two days and I am satisfied.
I wrote another review about Zero Glide and my Gold Tone OB 150 banjo. As many already know the Zero Glide Nut is standard equipment on the OB 150 banjo. Gold Tone has this nut on other instruments too. I like this nut system for a lot of reasons. I installed a Zero Glide nut on my Martin D custom and I even installed a Zero Glide on my Washburn M3SWK F body mandolin. Those stock plastic nuts on many of the entry level pro instruments just does not cut it. You are cheating yourself and your audience out of a lot of tone and sweetness that ears should be hearing. The Zero Glide nut does a world of wonders for my instruments. Do yourself a favor and get one on your axe. You may love it. I know I do. I am addicted to Zero Glide.
