ZB-27F Unslotted Replacement Nut for Basses (Common on Fender P-Bass)

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
