5 Obvious Signs Your Guitar Neck Is Warped Or Bowed

Not every guitarist knows the obvious signs of a warped guitar neck, especially if you only started playing recently. Some signs of a warped neck are much easier to spot than others. Regular maintenance and thoroughly checking your guitar for any signs that the neck may be warped can save you a lot of work and money going forward.

A warped or bowed guitar neck is a condition where the neck of the guitar curves or bends in a concave manner, creating a noticeable gap between the strings and the frets. This can result in a higher action, making it more difficult to play the guitar.

Here are five obvious signs that your guitar neck is warped:

  1. Your guitar neck is twisted.
  2. The frets on your guitar are misaligned.
  3. You are experiencing fret buzz.
  4. Your guitar is out of tune.
  5. Your guitar has become wet.

A warped neck can affect your guitar’s sound, and the last thing you want is to have to buy a costly replacement. In this article, we will take a deeper look at these five signs and how catching them early on can save you a lot of work and money going forward.

What Is A Warped Guitar Neck?

A warped guitar neck is when the neck of the guitar becomes bent or bowed, leading to issues with playing and sound quality. The neck of the guitar is made of wood, which can expand or contract due to changes in temperature and humidity levels.

In some cases, the tension of the strings can also cause the neck to bend. A warped guitar neck can cause problems such as high action, string buzz, and difficulty in playing. It’s important to monitor the humidity levels and store your guitar properly to prevent warping.

1. Your Guitar Neck Is Twisted Causing a Warped & Bowed Guitar Neck

Playing on a guitar with a warped neck is uncomfortable and sometimes impossible. If the neck is significantly warped, the strings will make a buzzing sound, and you won’t be able to tune your guitar. If the neck is only slightly warped, you might be able to play on it without any issues.

It is possible to fix a warped neck yourself if you catch it in time, but if your guitar’s neck is seriously damaged, you might have to take it to your local guitar shop to get it fixed or even replaced. Repair costs vary and can be extremely expensive, so it is always best to properly maintain your guitar to avoid a twisted neck.

The first and most obvious sign you should look out for is a twisted neck. You can follow these easy steps to check if your guitar neck is twisted:

  1. Take your guitar, place it on a table, and sit in front of the instrument. Your guitar can be fully strung for this, so don’t worry about removing the strings.
  2. Make sure the lighting in the room is good. Natural light is the best light source, so position the table and guitar in front of a window if possible.
  3. Bend down so that your eyes are level with the guitar, and look down the guitar neck, from the tuning keys to the sound hole.
  4. Turn the guitar around and check it from the other side, looking from the soundhole to the tuning keys.

You can spot a significantly warped guitar neck easily. One side of the guitar neck will be lower than the other, meaning the middle of the neck will be higher than the body or headstock.

On the other hand, if your guitar neck shows only slight warping, you might not be able to see it as clearly. You can try using the shadows of the strings as a guide to see if there is a warp, but this might be difficult for the untrained eye.

If you can’t see any warp but are sure that there is something wrong with the neck of your guitar, you can take it to your local guitar shop. They will usually have an expert who can look at your guitar for you; however, it is possible to play the guitar with a slight twist without any issues.

Straightening a Twisted Guitar Neck

Straightening a twisted guitar neck is possible; you will, however, need the right tools for the job. Repair costs can be expensive, but if you aren’t sure that you can fix your guitar neck yourself, it is better to take it to a repair shop because you might damage it more. 

If you are a handy person and enjoy doing DIY projects and woodwork, fixing your guitar’s twisted neck should be easy and maybe even fun.

You can use heat and pressure to correct the twist in your guitar neck.

  1. Start by removing the strings from your guitar and placing them somewhere for safekeeping. Do not bend them as this can cause them to break next time you are playing.
  2. Now remove the fretboard. You can do this by using the heat from a clothing iron to melt the glue. 
  3. Once you have removed the fretboard, you can secure the guitar’s neck in your straightening jig. If you don’t have a jig, you can use your woodworking skills to build one or use some clamps instead.
