How to Tell if Your Guitar’s Neck Is Warped

How To Tell If Your Guitar’s Neck Is Warped

Most times, you might not even notice the change in the guitar’s appearance. But if you’ve been playing that particular instrument for a while, there’s a chance that you’ll hear the change in tone and melody. Here are two ways to confirm if your guitar’s neck is truly warped.

The Eye Test

If you lay your guitar flat down and look at it, you might think it’s as flat as the day you bought it. To notice the warped neck using the eye test method, stand the guitar and ensure it’s straight.

Proceed to look down at the guitar from the headstock. If possible, do this outside in the daytime or in a place with proper lighting. Because most times, the differences might be hard to notice.

If the guitar’s neck is warped, you’ll notice that one side is lower than the other. It’ll basically look like a twisting or winding staircase.

If you conduct the eye test under good lighting, you should be able to notice a warped neck because it’s by far the most used method and has proven to be efficient.  

Feeler Gauges 

A feeler gauge is an important tool every guitarist should own. Besides using it to check if your guitar’s neck is warped, you can also check the guitar’s string height. 

Feeler gauges are thin metallic pieces that are slotted into narrow gaps or holes to measure them. These measurements are mostly in thousandths of an inch or hundredths of a millimeter. 

Every feeler gauge has its measurement, and you’ll need to know the relief at each part of the neck before choosing a gauge to use. This is important because using a gauge bigger than the neck relief can damage your guitar or gauge.

Now, insert the gauge underneath the string on top of each fret across several parts of your guitar’s neck. That will check the difference in height between the string and the fret. You can do this simultaneously with a six-inch Stewmac ruler to confirm your readings.

Surely there’ll be tiny gaps between different points on the neck, but if you notice that the gaps are too wide, then the guitar’s neck is probably warped.

Editor’s Comment

The relief on acoustic and electric guitars is usually between 8-10 thousandths of an inch.

How To Prevent Neck Warping

Preventing a guitar’s neck from warping is all about good maintenance. Here are some tips to help you.

  • Do not store the guitar in environments with high humidity, like your garage or basement. 
  • Avoid leaving your guitar outside on sunny days. Unless you’re playing outside, you should keep your guitar away from sunlight. Also, avoid keeping it close to any device that emits heat.
  • Stop keeping your guitar in your car’s trunk. A car’s trunk is either too humid or too hot, which might cause irreversible damage to your guitar’s neck.
