Anatomy of Fret Buzz
Fret buzz is caused by vibrations of the strings against the frets. This can happen for a variety of reasons, including:
- Incorrect string height: The strings may be too low or too high, causing them to buzz against the frets.
- Worn or uneven frets: The frets may have become worn or uneven, causing inconsistencies in string height.
- Neck angle: The angle of the guitar’s neck may be incorrect, putting excessive pressure on the strings.
- Loose bridge: A loose or poorly positioned bridge can allow the strings to vibrate excessively.
- Improper truss rod adjustment: The truss rod is a metal rod inside the guitar’s neck that helps to adjust the curvature of the neck. An improper adjustment can cause the neck to bow or warp, creating fret buzz.
Diagnosing Fret Buzz
Before you can fix fret buzz, you need to diagnose the cause. To do this, you can:
- Identify the specific frets: Buzzing frets can be isolated by playing each fret on all six strings.
- Check the string height: Use a ruler or feeler gauge to measure the distance between the strings and the frets. The height should be approximately 0.015-0.020 inches.
- Inspect the frets: Look for any dents, flat spots, or unevenness. Worn frets may require leveling and re-crowning.
- Check the neck angle: You can use a straight edge or a special neck angle gauge to check the angle of the neck. The ideal angle is typically between 0 and 1.5 degrees.
- Tighten the bridge: Make sure the guitar bridge is securely fastened to the body. If it’s loose, it can cause the strings to buzz against the frets.
- Adjust the truss rod: Using a truss rod wrench, adjust the rod until the neck has a slight back-bow. This will help to raise the strings and reduce fret buzz.
Expert Tips and Advice
Once you’ve diagnosed the cause, it’s time to fix the fret buzz. Here are some tips from professional luthiers:
- Use a fret leveling file: For worn or uneven frets, a fret leveling file is used to gently and evenly level the frets.
- Crown the frets: After leveling, use a fine-grit sandpaper or a crowning file to shape and smooth the tops of the frets.
- Adjust the string height: Use a bridge wrench or hex key to raise or lower the bridge until the string height is correct.
- Lubricate the nut: Applying a small amount of pencil lead or nut lubricant to the string slots can help to reduce friction and prevent buzz.
- Check for other issues: If you’ve tried all of the above and you still have fret buzz, check for other potential issues, such as a warped neck, damaged bridge, or loose truss rod.
