How much gap should be there between fretboard and strings?

The distance between the strings and the neck at the 12th fret should be about 1.6 millimetres (0.063 in), or the width of a dime. Hold the flat end of a ruler against the neck and measure how high the strings are. If the strings are further than 1.6 millimetres (0.063 in), (high action) you need to lower the bridge.

Which way do you adjust intonation?

Turning the screw clockwise increases the length of the guitar string. If the fretted 12th fret note is sharp, adjusting the screw clockwise will improve intonation. Turning the screw anti-clockwise decreases the length of the guitar string.

What is the distance between the strings and the fretboard called?

action
In the guitar and similar instruments, the action is the distance between the fretboard and the string, which determines how easy it is to sound notes when pressure is applied with the fingertips.

Does changing string height affect intonation?

Your guitar’s action height directly affects intonation. If the action is too high, it will throw your intonation out.

Does string gauge affect intonation?

String gauge does affect intonation, but just a little bit. Having a perfectly intonated instrument is almost impossible to achieve. There are too many factors accounting for the intonation change. Action height, bridge saddle position, neck radius, nut position and height, and so on.

How do you intonate a guitar?

“Adjusting an instrument’s intonation consists of setting the bridge saddles to produce the note at the 12th fret exactly an octave higher than that of the open string. With the aid of an electronic or digital tuner, compare either the open string or the octave harmonic at the 12th fret with the fretted octave at the 12th fret.

What is the purpose of intonation on a guitar?

The purpose of intonation is to set the octave to exactly one half of the scale length. If you measure from the nut to the twelfth fret on a 25.5″ scale guitar you will see 12 3/4″, or one half of 25.5″. So it must be 12 3/4″ from 12th fret to the saddle ,right?

How do you intonate a fretted note?

If the fretted note is sharp, move the saddle away from the pickups and fret board; if it is flat, move the saddle toward the pickups and fret board.” I always assumed that proper intonation was determined by comparing the octave harmonic at the 12th fret with the fretted octave at the 12th fret.

How to tell if a 12th fret harmonic is out of tune?

If the open string is in tune, the 12th fret harmonic will be also. If one is out of tune, so is the other. You can compare the 12th fretted note to either of the other two. I compare to the open strings, they wobble more in the pups magnetic field than a harmonic would.
