I was having a very hard time finding the right nut replacement for my mandolin. Finally found this one at StewMac. Have never used the zero glide before, but this one works great. Had a good deal of sanding to do for a perfect fit, but it works great and sound is super on my mando. Thanks guys!!

Pretty easy to install - sand it down to fit - pick the fret that matches the rest of your fretboard - couldn't be easier!

Resolves the nut-string height issue with a simple and easy installation. Worked perfect on my Heritage 16.

I bought the mandolin version and fitted it to my Gibson. There's a lot of extra material to remove, but the result was great. Easier tuning (the old nut had tight slots for the A strings), better intonation. Later I used one of the extra frets in the package to fix a tenor guitar. For that, I simply filed the necessary ledges in the existing nut and widened the string slots. It would be nice if Stew-Mac would also sell the offset tang frets separately, for retrofitting to an existing nut.
