How to Intonate a Guitar from Scratch - Step-by-Step Guide

Welcome to this tutorial on how to intonate a guitar from scratch. In this step-by-step guide by Phillip McKnight, we will walk you through the process of achieving proper intonation for your guitar. Intonation is crucial for ensuring that your instrument plays in tune all across the fretboard. Let's get started!

Step 1: Measure the Saddles

Before we begin, gather the necessary tools:

• Tuner (e.g., Peterson strobe tuner, quality floor tuner)
• Measuring tape
• Screwdriver (Phillips or flathead, depending on your guitar)

Here's how to measure the saddles:

1. Identify the scale length of your guitar. For example, a Fender or Squier guitar typically has a 25.5-inch scale length.
2. Measure from the inside of the nut to the tip of the saddle for the low E string.
3. Ensure it matches the correct scale length. Different guitar models may have variations in scale length, so refer to your guitar's specifications.

Step 2: Tune the String

Now, let's tune the string:

1. Start with the low E string.
2. Use your tuner to tune the string until it is perfectly in tune.

Step 3: Pluck the String

Pluck the string at the twelfth fret and observe the pitch. If the guitar is sharp:

• If your tuner's needle is pointing to the right (or the digital display shows a higher value), adjust the saddle towards the headstock.
• If your tuner's needle is pointing to the left (or the digital display shows a lower value), bring the saddle towards the bridge.

Step 4: Adjust the String

Make small adjustments to achieve proper intonation:

• If the note is sharp, loosen the string slightly and move the saddle towards the headstock.
• If the note is flat, loosen the string slightly and bring the saddle towards the bridge or the back of the guitar.
• Remember to make incremental adjustments, such as half a millimeter at a time.
• Retune the string and check the intonation at the twelfth fret.
• Repeat the process until the note at the twelfth fret is in tune.

Step 5: Repeat for Other Strings

Follow the same process for each of the remaining strings on your guitar. Take your time and ensure the intonation is accurate for each string.

Troubleshooting

If you encounter issues with intonation, try these troubleshooting steps:

• If adjusting the saddle doesn't resolve the issue, remeasure the scale length and start from scratch.
• Keep in mind that different factors, such as string height and angles, may require deviations from the standard procedures.

You have learned how to intonate a guitar from scratch. Proper intonation is essential for achieving accurate pitch and enjoyable playing experience. Remember, there may be variations depending on your guitar model, so always refer to the specifications. Feel free to experiment and find the intonation setup that suits your playing style. Enjoy playing in tune!
