Intonating an electric guitar involves adjusting the length of the strings so that they play in tune across the fretboard. This process ensures that chords and notes sound harmonically correct at various positions on the guitar neck.

Key takeaways
- Understanding Guitar Intonation is about recognizing the importance of having each string on the guitar produce the correct pitch at every fret.
- Checking and Diagnosing Intonation Issues requires comparing the pitch of a fretted note at the 12th fret to the natural harmonic at the same fret, identifying if the guitar is intonated poorly.
- Adjusting Saddle Position is crucial for proper intonation; moving the saddle forward or backward can correct sharp or flat notes respectively.
- Maintaining Proper Intonation enhances the overall sound, making learning songs and performing more enjoyable.
Understanding Guitar Intonation
Guitar intonation is the accuracy of the pitches produced along the entire length of the guitar string, ensuring that both the open-string pitch and fretted notes are in tune.
Proper intonation is essential for the playability and sound quality of an electric guitar, as it affects whether chords and melody lines sound in tune as you move up the neck.
The relationship between the open string pitch and the twelfth fret pitch is a critical indicator of intonation; if these two pitches are not an octave apart, intonation adjustment is required.
Saddle adjustment is a common method for correcting intonation discrepancies, and fine-tuning the length of the strings to achieve harmonious sound.
Checking and Diagnosing Intonation Issues
Checking guitar intonation meticulously with a tuner involves a clear sequence of steps to ensure each string is precisely in tune.
Begin by tuning the open strings to the desired pitch, then assess the intonation by comparing this with the pitch of the natural harmonic or fretted note at the 12th fret.
If the 12th fret note registers sharp (too high) compared to the open string, the string’s effective length must be increased by moving the saddle back.
Conversely, if it is flat (too low), the saddle needs to be moved forward. This intonation check and subsequent saddle movement ensure each note plays true.
Adjusting Saddle Position for Proper Intonation
Different types of guitar bridges require specific methods of saddle adjustment to achieve perfect guitar intonation.
Fender-style bridges typically have individual saddles with screws that can be turned to move the saddle forward or backward, while Gibson-style bridges might use a thumbwheel or a screwdriver for adjustments.
The string action—the height of the strings over the fretboard—can also influence intonation, necessitating a balance between comfortable playability and intonational accuracy.
After initial adjustments, repeated fine-tuning of the saddle position for every string is often necessary to dial in the intonation precisely. Regular maintenance, like changing strings and allowing the guitar to settle after adjustments, helps in maintaining intonation.
