I've used this for over a month and I'm more happy now than when I first installed it. The intonation on my acoustic is better than it ever was...you can fine tune the saddle almost dead on for intonation. One suggestion.....be sure to glue in the zero fret with a few drops of glue once you get the guitar right. I was working on my guitar on and off for a month and didn't glue in the zero fret. I was taking the strings on and off. Every time you reinstall the zero fret it will be in a slightly different place. String against fret will cause a slightly different indentation in the zero fret. You want the string to stay in the same spot on the zero fret.

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.

works like a charm for the stuff I do at weekend gigs,from flutter trem to dive whammy , but most of all, I no longer hear that creaking sound by the nut when using my tremolo and it stays in tune well along with my Wilkinson VSVG Tremolo.

Easy to install for me cause I work for two guitar shops on a on/off basis and am use to making bone nuts from scratch,so if you've never done guitar nut work before I suggest taking it to a well trusted guitar shop with a good tech. It does take patience if you want it to look like a pro and function the way its suppose to. Highly recommend it along with a Wilkinson VSVG and a high gear ratio tuners.. Be buying more soon for my other guitars....

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
