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.
Wow, what an innovation! This product eliminates the critical process of nut filing completely disappear to be replaced by a zero fret which enhances the sound of your guitar. It is not without some challenges in installation, but once completed your guitar just sounds and plays better.
I play fingerstyle guitar. My favorite guitar is a Gretsch 5420 Electromatic . For some reason the designers at Gretsch moved away from the zero fret. When You string up with 10's or 9's I guess it probably doesn't matter much because the first position will be easy with light gauge strings. My touch and style of playing requires .012's. With heavier strings while the 5420 is beautiful to see and hear the first position was challenging to play. I installed the zero glide following the instructions in the package and to my amazing pleasure the 5420 played like my '66 Nashville used to. I couldn't be happier. Thanks to the people that designed this product. The tone is great the tuning is improved and the first position action is second to none.
