Adjusting Intonation on Modern Guitars: A Comprehensive Guide

As a guitar player, one of the most important aspects of your instrument is its intonation. It can make or break the sound of your playing, and if it's not properly adjusted, it can be frustrating and discouraging. In this article, we will dive into the world of modern guitars and explore how to adjust their intonation for optimal sound and playability.

The Importance of Intonation

Before we get into the specifics of adjusting intonation on modern guitars, let's first understand why it's so important. Intonation refers to the accuracy of the pitch produced by each fret on the guitar.

When a guitar is properly intonated, each note played on each fret will be in tune with each other. This is crucial for playing in tune with other musicians and for creating a pleasing sound. On modern guitars, intonation is affected by several factors such as string gauge, string height, and neck relief. These factors can change over time due to temperature and humidity changes, as well as regular wear and tear. That's why it's important to regularly check and adjust your guitar's intonation.

Tools You'll Need

Before we begin adjusting intonation on your modern guitar, you'll need a few tools:
  • Guitar tuner: This is essential for accurately tuning your guitar.
  • Screwdriver: You'll need this to adjust the saddle screws on your guitar.
  • Ruler: A ruler or measuring tape will help you measure the distance between the frets and strings.
  • Guitar capo: This will come in handy when adjusting the intonation on the higher frets.

Adjusting Intonation on Modern Guitars

Now that you have all the necessary tools, let's dive into the steps for adjusting intonation on your modern guitar:

Step 1: Tune Your Guitar

The first step is to make sure your guitar is in tune.

Use your guitar tuner to tune each string to its correct pitch.

Step 2: Check the 12th Fret

The 12th fret is a good starting point for checking intonation. Play the open string and then play the same string on the 12th fret. If the two notes are not in tune, you'll need to adjust the saddle screw for that string.

Step 3: Adjust the Saddle Screw

Using your screwdriver, turn the saddle screw clockwise to raise the pitch or counterclockwise to lower it. Make small adjustments and retune the string until the open string and 12th fret note are in tune with each other.

Step 4: Check Other Frets

Once you have adjusted the intonation for the 12th fret, check other frets as well.

Play each string on different frets and make sure they are all in tune with each other. If not, make small adjustments to the saddle screws until they are.

Step 5: Repeat for Each String

Repeat steps 2-4 for each string on your guitar. Remember to tune your guitar after each adjustment.

Step 6: Check Higher Frets

Once you have adjusted the intonation for the lower frets, it's time to check the higher frets. Use your guitar capo to play each string on the 12th fret and check its intonation.

If needed, make small adjustments to the saddle screws until the notes are in tune.

Tips for Adjusting Intonation

Here are a few tips to keep in mind while adjusting intonation on your modern guitar:
  • Make small adjustments: It's important to make small adjustments to the saddle screws. This will help you fine-tune the intonation without making drastic changes.
  • Check each string multiple times: After making an adjustment, tune your guitar and check the intonation again. Repeat this process until all strings are in tune with each other.
  • Be patient: Adjusting intonation can be a time-consuming process, but it's worth it for a well-tuned guitar.

When to Seek Professional Help

If you're new to adjusting intonation or if you're having trouble getting your guitar in tune, it's always best to seek professional help. A guitar technician will have the necessary tools and expertise to properly adjust your guitar's intonation.

In Conclusion

Adjusting intonation on modern guitars is an essential skill for any guitar player.

By following these steps and tips, you can ensure that your guitar is always in tune and ready to play. Remember to regularly check and adjust your guitar's intonation for optimal sound and playability.
