Changing the action rod inside an acoustic guitar is a relatively simple process that can be completed in a few minutes. The action rod is a metal rod that runs through the neck of the guitar and helps to adjust the string height. By adjusting the action rod, you can make the guitar easier or more difficult to play.
There are a few reasons why you might want to change the action rod inside your acoustic guitar. For example, if the strings are too high, it can make it difficult to fret the notes. Conversely, if the strings are too low, they may buzz against the frets. By adjusting the action rod, you can find the perfect string height for your playing style.
To change the action rod inside your acoustic guitar, you will need a few tools, including a truss rod wrench, a hex key, and a screwdriver. You will also need to know the specific measurements for your guitar. Once you have gathered your tools and measurements, you can follow these steps:
- Loosen the truss rod nut by turning it counterclockwise with the truss rod wrench.
- Insert the hex key into the action rod and turn it clockwise to raise the strings or counterclockwise to lower the strings.
- Tighten the truss rod nut by turning it clockwise with the truss rod wrench.
- Check the string height and make any necessary adjustments.
Once you have finished adjusting the action rod, you should retune your guitar and check the intonation. If the intonation is off, you may need to adjust the bridge saddles.

3. Measurements
In the context of “How To Change The Action Rod Inside An Acoustic Guitar,” understanding the specific measurements for your guitar’s action is crucial for achieving optimal playability and sound.
- String Height Measurement: Measuring the string height, which is the distance between the strings and the fretboard, is essential for determining the action of the guitar. The ideal string height varies depending on the guitar and playing style, but generally, lower string height makes the guitar easier to play, while higher string height provides more volume and sustain.
- Neck Relief Measurement: The neck relief refers to the curvature of the guitar’s neck. Measuring the neck relief ensures that the neck is set to the correct curvature, which affects the playability and intonation of the guitar. The ideal neck relief varies depending on the guitar and playing style, but generally, a slight forward bow (convex shape) is desired.
- Fretboard Radius Measurement: The fretboard radius refers to the curvature of the fretboard from side to side. Measuring the fretboard radius is important for ensuring that the strings are properly seated in the nut and bridge saddles, and that the guitar is intonated correctly. The fretboard radius varies depending on the guitar and playing style, but common measurements include 9.5 inches, 10 inches, and 12 inches.
- Truss Rod Adjustment: The truss rod is a metal rod that runs through the neck of the guitar and is used to adjust the neck relief. By tightening or loosening the truss rod, the neck relief can be adjusted to achieve the desired curvature. The amount of adjustment needed will vary depending on the guitar and the desired neck relief.
Understanding these measurements and how they relate to the action rod adjustment is essential for optimizing the playability and sound of your acoustic guitar.
4. String height
In the context of “How To Change The Action Rod Inside An Acoustic Guitar,” understanding string height is crucial for optimizing the guitar’s playability and sound. String height refers to the distance between the strings and the fretboard, and it can be adjusted by changing the action rod.
- Playability: String height directly affects the ease of playing the guitar. Lower string height makes it easier to fret notes, especially for beginners or players with smaller hands. Higher string height can make it more difficult to fret notes, but it can also provide more volume and sustain.
- Intonation: String height also affects the intonation of the guitar, which refers to the accuracy of the notes played at different frets. If the string height is too low, the strings may buzz against the frets, resulting in incorrect intonation. If the string height is too high, the strings may not be able to properly contact the frets, also resulting in incorrect intonation.
- Tone: String height can subtly affect the tone of the guitar. Lower string height can produce a brighter, more articulate tone, while higher string height can produce a warmer, more mellow tone.
- Adjusting the Action Rod: The action rod is a metal rod that runs through the neck of the guitar and is used to adjust the neck relief. By tightening or loosening the action rod, the neck relief can be adjusted, which in turn affects the string height. Adjusting the action rod is a relatively simple process that can be done with a few basic tools.
Understanding the relationship between string height and the action rod is essential for guitarists who want to optimize the playability, sound, and intonation of their instrument.
5. Intonation
In the context of “How To Change The Action Rod Inside An Acoustic Guitar,” intonation plays a crucial role in ensuring that the guitar produces accurate and consistent notes across the entire fretboard. Intonation is the adjustment of the string length to ensure that each string plays the correct pitch when fretted at different positions.
- Fret Accuracy: Intonation directly affects the accuracy of the notes played at different frets. If the intonation is off, the notes played at certain frets may be sharp or flat, resulting in incorrect pitch and diminished sound quality.
- Playability: Proper intonation enhances the playability of the guitar, making it easier to play in tune and produce clear, resonant notes. Accurate intonation allows guitarists to play chords and melodies with confidence, knowing that the notes will be in tune.
- Action Rod Adjustment: The action rod can influence intonation by adjusting the neck relief, which is the curvature of the neck. Changes in neck relief can affect the string height and the distance between the strings and the frets, which in turn can impact intonation.
- String Height: String height is another factor that can affect intonation. If the string height is too high, the strings may not be able to properly contact the frets, resulting in incorrect intonation. Conversely, if the string height is too low, the strings may buzz against the frets, also affecting intonation.
By understanding the relationship between intonation and the action rod, guitarists can make informed adjustments to achieve optimal intonation and improve the overall sound and playability of their acoustic guitars.
