If the note on the 12th fret is flat, that would mean that the saddle for that string needs to be moved forward toward the headstock. If the note on the 12th fret is sharp, that would mean that the saddle for that string needs to be moved back away from the headstock.
Herein, 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.
Correspondingly, how do you check Acoustic intonation?
People also ask, how do you fix a sharp intonation on an acoustic guitar?
It can be controlled by tightening or loosening the truss rod, which is located in the neck. Essentially, the technician is trying to get everything right before actually adjusting the acoustic guitar’s intonation. This removes the extra variables and makes it easier to dial in the intonation.
How do you fix sharp intonation?
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. If the fretted 12th fret note is flat, adjusting the screw clockwise will improve intonation.
How do you play 12th fret harmonics?
To play a harmonic place your finger directly above the 12th fret on the 6th String (thickest string).

Is my guitar’s intonation off?
When an instrument is properly intonated, all the open strings and every note on the fretboard sound at their correct pitches. If your guitar still sounds noticeably out of tune even after you’ve tuned the open strings, the intonation is off—that is, the instrument is out of tune with itself.
Where is the 12th fret on a guitar?
Why does my guitar play sharp?
When a string is pressed down, fretted, its total length rises and so does its tension. This increased tension will cause the note to play sharp. Higher action means more tension which causes the note to play sharp. Low action means less tension.
Why is my guitar always sharp?
With steel strings on a wooden guitar, the strings go sharp when it cools down. The thermal coefficient of expansion of the steel in the strings is much greater than that of wood, so they shrink more and get tighter.
Why is my guitar out of tune at the 12th fret?
Guitar intonation explained
If the note at the 12th fret is out of tune (more than a few cents off) from the open note, you probably need to adjust your intonation. When intonation is set, the string length is adjusted by moving the saddle closer or farther from the bridge.
