Göldo Zero Glide ZGZS5 Nut

I have often wondered why all guitars did not have a a Zero fret! Some do, but not all? Why? Now the ZerO Glide Nut from GoldTone has come along and I have just fitted one to my Taylor Dan Crary Signature model. According to the advertising blurb improvement will be found in three areas: action at 1st position/fret - intonation and open string tone. I agree wholeheartedly with all three claims and am very pleased, and impressed, with the result I have obtained! The guitar sounds brighter on open string chords - with noticeably improved open string tone - and the1st fret action is perfect. The ZerO Glide Nut I needed was the Z-S-15 and it fits to perfection. This is very precisely engineered product and does exactly what it claims. I fitted it myself. It took a lot longer than I anticipated (a lot of sanding needed on four faces of the nut), but, it was worth it. I intend, in the near future, to repeat the exercise on my other guitars. Well done Zero Glide Nut! it was a long wait but worth it in the end!
