The Zero Glide Replacement Nut System borrows the "zero fret" concept to reduce string contact in the nut by up to 93%, increasing tuning stability, playability, and open string tone. It only takes a few minutes to install with absolutely no permanent alteration to your instrument. For Fender Style "Jazz Bass".
Also available in Black Delrin.
Note: May not fit specific models. Check the sizing guide to be sure.
Just put one of these on an old beater of a cheap strat-clone kit that I use to experiment with "creative" wiring. Suddenly its in tune up and down the neck and stays that way after using the trem as well. It cost half the price of the kit but it has significantly improved the value of the instrument to me. It required a little sanding of the back of the nut but nothing drastic. I dont have many dedicated luthier tools so the fret wire is not trimmed perfectly (but the look is in keeping with the overall "relic'd" appearance of the guitar). The question now becomes can I get a discount if I order these in bulk?
