Electric Guitar Intonation: Troubleshooting the 12th Fret
Understanding Intonation
Intonation refers to the accuracy of the pitch of each note on the guitar. When a guitar is properly intonated, all the open strings and every note on the fretboard should sound at their correct pitches.
The Importance of the 12th Fret
The 12th fret is a crucial reference point for checking intonation on the guitar. It should be in tune with the open string’s frequency.
Checking Intonation on the 12th Fret
To check the intonation on the 12th fret, keep your guitar plugged into a tuner, fret the 12th fret, and play each string. If the tuning of the 12th fret matches the open string’s tuning, then your guitar is properly intonated.
Adjusting the Intonation
If there is a tuning discrepancy between the fretted 12th-fret note and the 12th-fret harmonic, the string is not correctly intonated and requires adjustment.
- If the fretted 12th-fret note is sharper than the 12th-fret harmonic, the string must be slightly lengthened by moving the bridge saddle farther from the nut until both pitches are correct.
- If the fretted 12th-fret note is flatter than the 12th-fret harmonic, the string must be slightly shortened by moving the bridge saddle toward the nut until both tunings read correctly.
The Meticulous Process of Intonation
Intonating a guitar can be a meticulous and time-consuming process, but it is an essential part of guitar maintenance. Periodic intonation adjustments are usually necessary due to environmental conditions and fluctuations in the guitar’s setup.
Remember that achieving proper intonation enhances your guitar’s sound, playability, and overall musical experience. By understanding and addressing intonation issues, you can ensure that your electric guitar delivers accurate and harmonically rich tones throughout the entire fretboard.

How do I check the intonation on the 12th fret of my electric guitar?
To check the intonation on the 12th fret, keep your guitar plugged into a tuner, fret the 12th fret on each string individually, and pluck the string. Observe the tuner’s display to see if the tuning of the 12th fret matches the open string’s tuning.
What should I do if there is a tuning discrepancy between the fretted 12th-fret note and the 12th-fret harmonic?
If there is a tuning discrepancy between the fretted 12th-fret note and the 12th-fret harmonic, it means that the string is not correctly intonated and requires adjustment.

How do I adjust the intonation on my electric guitar?
To adjust the intonation on your electric guitar, you can move the bridge saddle. If the string needs to be lengthened, move the bridge saddle farther from the nut. If the string needs to be shortened, move the bridge saddle toward the nut. Make these adjustments until both the fretted 12th-fret note and the 12th-fret harmonic are in tune.
How often should I check and adjust the intonation on my electric guitar?
Periodic intonation adjustments are usually necessary due to environmental conditions and fluctuations in the guitar’s setup. It is recommended to check and adjust the intonation whenever you change string gauges, adjust the action, or notice significant tuning discrepancies on specific frets.
Can I adjust the intonation on my electric guitar myself, or should I seek professional help?
Adjusting the intonation on an electric guitar can be done by individuals with some technical knowledge and experience. However, if you’re unsure or uncomfortable with making adjustments, it’s always a good idea to seek professional help from a guitar technician or luthier.
