Gathering the necessary tools

To intonate your guitar correctly, you will need a few essential tools. Firstly, you will need either an acoustic or an electric guitar, depending on your preference. Secondly, a guitar tuner is crucial to ensure accurate tuning throughout the intonation process. Additionally, a screwdriver will be necessary for making adjustments to the saddle. To measure the string action, you will need a string action gauge. Another tool you will require is a Phillips screwdriver, which will be used to adjust the saddle screws. Finally, make sure to have a set of new guitar strings on hand for any replacements that may be necessary during the intonation process.

Understanding guitar intonation

What is intonation?

Intonation refers to the accuracy of the guitar’s pitch across the entire fretboard. It is the ability of the guitar to play in tune with itself, meaning that each note should sound correctly in relation to other notes. Guitar intonation involves adjusting the string length to achieve precise pitch alignment across various frets.

Why is intonation important?

Proper intonation is essential for ensuring that your guitar sounds harmonious and in tune. Without good intonation, chords may sound dissonant, and melodies may become distorted. Correct intonation allows for more accurate playing, enabling you to play in different positions on the neck without sacrificing correct pitch. Whether you’re performing solo or playing in a band, maintaining accurate intonation is crucial for sounding professional.

How does intonation affect guitar playability?

When the intonation is off, you may find it challenging to play certain chords or progressions in tune. This can be frustrating and hinder your progress as a guitarist. Correct intonation ensures that the fretted notes on each string correspond perfectly to the harmonic pitches, allowing for more precise and comfortable playing. Whether you’re a beginner or an experienced player, a well-intonated guitar significantly enhances your playing experience.

Checking initial intonation

Before adjusting the intonation, you must first determine the current state of your guitar’s intonation. Follow these steps to check the initial intonation of your instrument:

Tuning the guitar

Start by tuning your guitar using a reliable guitar tuner. Ensure that all the strings are fully tuned and in proper pitch before proceeding.

Playing harmonic on the 12th fret

Once your guitar is in tune, lightly touch the string directly over the 12th fret and pluck the string. This technique produces a harmonic tone. Repeat this process for each string.

Comparing harmonic pitch with fretted note

After playing the harmonic, fret the string at the 12th fret and pluck it again. Listen carefully and compare the pitch of the harmonic with the pitch of the fretted note. If the fretted note sounds sharply higher or flatter compared to the harmonic, your guitar’s intonation needs adjustment.

Adjusting the string length

To correct any intonation issues, you will need to adjust the string length by manipulating the saddle. Follow these steps to adjust the string length on the guitar:

Locating the string saddle

The saddle is located on the bridge of your guitar, where the strings are anchored. Each string has an individual saddle responsible for setting its length.

Saddle adjustment screws

On most electric and some acoustic guitars, the saddle can be adjusted using small screws located either at the front or back of the bridge. These screws control the forward or backward movement of the saddle, altering the string length.

Determine whether to lengthen or shorten the string

Based on your initial intonation check, if the pitch of the fretted note at the 12th fret is too high compared to the harmonic, the string length needs to be lengthened. Conversely, if the fretted note is too low, the string length needs to be shortened.

Use the screwdriver to adjust the saddle

Using a Phillips screwdriver, turn the saddle adjustment screws in the appropriate direction to achieve the desired string length adjustment. Make small adjustments at a time, frequently rechecking the intonation until it is correct. Continue this process for each string that requires adjustment.

Rechecking the intonation

Once you have made the necessary saddle adjustments, it is crucial to recheck the intonation to ensure it has been corrected accurately. Follow these steps to recheck the intonation:

Tuning the guitar again

Begin by tuning your guitar once more, ensuring all the strings are in proper pitch.

Playing harmonic on the 12th fret again

Repeat the process of playing a harmonic directly over the 12th fret for each string.

Comparing harmonic pitch with fretted note again

Fret each string at the 12th fret and pluck it, comparing the pitch of the harmonic with the pitch of the fretted note. This comparison will determine if further adjustments to the string length are necessary.

Adjusting individual strings

During the rechecking process, you may identify some individual strings that still require fine-tuning. Follow these steps to adjust individual strings:

Identify which strings need adjustment

Based on your comparison of the harmonic and fretted note pitches, identify any strings that are still out of intonation and need adjustment.

Loosen the string

To adjust an individual string, you will need to loosen it slightly. Use the appropriate tool, such as a string winder, to loosen the string tension.

Move the saddle forward or backward

Once the string is adequately loosened, use the screwdriver to make slight adjustments to the saddle position, either moving it forward or backward.

Retighten the string

After adjusting the saddle, retighten the string to its proper tension using the appropriate tool. Be cautious not to overtighten, as it can lead to string breakage.

Checking overall tuning

After adjusting the intonation of individual strings, it is crucial to recheck the overall tuning of the guitar. Follow these steps to ensure accurate tuning:

Tuning all strings again

Revisit each string and verify that they are all tuned correctly using your guitar tuner. Pay close attention to each string’s pitch to ensure accurate tuning.

Playing open chords and checking for any issues

Once all the strings are properly tuned, play some open chords and check for any remaining intonation issues. Pay attention to the harmony of the chords and listen for any notes that sound dissonant or out of tune. Should you notice any issues, reevaluate the intonation and make any necessary adjustments.

Replacing guitar strings

Sometimes, resolving intonation issues may require replacing old strings with new ones. Follow these steps to replace the strings on your guitar:

Unwinding old strings

Begin by carefully unwinding the old strings from the tuning pegs. Make sure to unwind them slowly and evenly to prevent damaging the guitar or injuring yourself.

Removing bridge pins (for acoustic guitars)

For acoustic guitars, you may need to remove the bridge pins holding the strings in place. Use a bridge pin puller or a pair of pliers to gently lift and remove the pins.

Threading new strings through the bridge

Feed one end of the new string through the appropriate bridge hole, making sure it is securely in place. Be careful not to over-tighten or damage the bridge while threading the strings.

Securing the strings and tuning

Once all the strings are threaded through the bridge, wind each string around its respective tuning peg, making sure they are secure. Begin tightening the strings while periodically tuning to maintain accurate pitch. Adjust the tension of each string until they are in tune.

Testing and fine-tuning

After replacing strings or making adjustments to the intonation, it is essential to test and fine-tune the guitar. Follow these steps to ensure optimal playability:

Playing different chords and scales

Experiment with playing various chords, scales, and melodies across different positions on the fretboard. Pay attention to the sound and feel of your playing, listening for any anomalies that may indicate ongoing intonation issues.

Listening for any anomalies

As you play, listen for any notes or chords that sound noticeably out of tune or dissonant. Make notes of any areas that require further attention during the fine-tuning process.

Making additional adjustments if needed

If you encounter any intonation issues or anomalies while playing, revisit the corresponding steps in the intonation process to make any necessary adjustments. Remember to make small adjustments and frequently check the intonation to achieve the desired results.

Seeking professional help

While intonating your guitar can be done at home with the right tools and patience, there may be instances where seeking professional assistance is beneficial. Consider the following factors when deciding whether to consult a professional luthier or guitar technician:
