CD said:How do you explain the Earvana compensated nut then?
SkuttleFunk said:simply described, intonation is a compensation to account for what happens to string pitch when you press down on a string. if you were to compensate at the nut, all of your work will only impact an open string (which does not need to be intonated, as you simply adjust the tuner until it is in pitch.) as soon as you fret any note, your intonated nut will no longer have any impact on the string's tuning, and your pitch will be off by as much as the compensation adjustment is off
all the best,
