i HAVE ONE O TFHE NICER IMPORT JOHNSON ACOUSTIC ELECTRIC CUTAWAY GUITARS . SOLID SPRUCE TOP. INDIAN ROSEWOOD BACK AND SIDES. SOMETIME BACK I WAS ADJUSTING THE TRUSS ROD AND THE END BROKE OFF. LUCKILY THE ACTION WASN'T TERRIBLE. THE REAL PROBLEM I WAS HAVING WAS WHEN I PLAYED AT CHURCH I SWITCH BACK AND FORTH FROM CAPO TO NO CAPO DEPENDING ON THE SONG CHOSEN. WHEN I TUNED MY GUITAR STANDARD IT WAS FINE AND SOUNDED PRETTY GOOD BUT WHEN I USED THE CAPO THE GUITAR WOULD BE SLIGHTLY OUT OF TUNE. i JUST HAPPENED ACROSS TE ZERO GLIDE AND FIGURED I HAD NOTHING TO LOSE SINCE I COULD RETURN THE NUT BACK TO ORIGINAL WITH NO PROBLEM. I GOT THE CORRECT NUT BY USING THE STRING GUIDE PRINT OUT. TOOK MY TIME FOLLOWED VIDEO INSTRUCTIONS AND MADE MINOR ADJUSTMENTS UNTIL I WAS DONE. I CANNOT TELL YOU HOW PLEASED I AM. NO MORE OUT OF TUNE WITH CAPO. CONSISTENT BRIGHTER SOUND AND MUCH BETTER ACTION. I WOULD RECOMMEND THIS PRODUCT TO ANYONE I AM EVEN THINKING OF PUTTING ONE ON MY 1963 GIBSON LG1 SINCE THERE IS NO PERMANENT CHANGE TO THE GUITAR. THANKS ZERO GLIDE

Installed in a vintage Japanese Custom Shop Fender Tele. Great low action and better tuning stability. Easy install as well. Thanks for a great product.

I put this on one guitar i built and promptly bought another for another guitar. Awesome product. Use them!

The bone nut was easy to install. I sanded the length and depth with a table sander. The instructions are complete and easy to follow. Four zero frets of different sizes are included in the banjo kit--you try the smallest and work your way up until you have no open string buzz. Use medium viscosity cyanoacrylate (available from Stewmac) so you have time to set the nut and fret properly. I'm pleased with the results, improved tone, and hammer-ons and pull-offs are more defined.
