One for Fender Telecaster, the other for Breedlove acoustic. Both of these guitars are top 10 instruments. The Zero Glide nut improvement came through as described on Youtube demos. So much better string action (lower with out any fret buzz) Clarity in open string tone chords and pulloff plucking, faster tuning to pitch, using electronic tuner, remaining in pitch once strings stretch has settled in. I took my time to install on both guitars about 2 hours for each instrument. Have new custom Guitar that I will 99% sure I will add this improvement to soon. I see this becoming a standard upgrade to many popular manufactures. Lastly the sustain in open chords on all strings cant be described.
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 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
