The skinny being that the Zero Glide Replacement Nut Systems borrows the “zero fret” concept to reduce nut friction by 93% increasing tuning stability, playability, and open string tone.
Easily installs in minutes with no permanent alteration to your fretted instrument whatsoever.
Available preslotted to fit common string spacings and unslotted to fit everything else.
Apparently, it'll be like the "zero fret" on various European instruments (Framus, Hagstrom, Hoyer, Hofner, etc.)...may put one on The Poorman's EM150, and if I like it, possibly my GM50 Gold Tone.
Anyone else try it/consider it?
