1. Keep Your Guitar in a Hardshell Case

When you’re not playing your guitar, you need to ensure that you’re at least keeping it safe. The best way to do so is by storing it in a hardshell case. If possible, lay the case flat, so there is no pressure on the guitar’s neck.

It might be irritating to constantly take your guitar out of its case to play and then put it back just to take it out an hour later, but it is the only fool-proof way to keep your guitar safe. Leaving your guitar lying around the house or outside makes it vulnerable to heat and humidity changes which can cause the neck to warp.

A hardshell guitar case like this Gator Cases Hard-Shell Wood Case (available on Amazon.com) will work perfectly. The hardshell case is durable, made from plywood, and is covered with ultra-durable black Tolex PVC. It has a spacious interior accessory compartment for all the necessary add-ons. This case in particular provides extra neck support and a plush cushioned lining for protection.

2. Use a Guitar Stand

If you don’t want to continuously put your guitar away throughout the day, you can invest in a guitar stand. These stands are specially made so your guitar will be supported on the lower bout.

Don’t ever place your guitar so that it is lying at an angle against a wall. It can cause the neck to warp. Instead, put the instrument on your guitar stand or lay it down flat on a clean, dry table.

You can get an Amazon Basics Guitar Folding Stand from Amazon.com. This frame will work for any guitar as it has three adjustable width settings. It’s lightweight, durable, and has soft foam arms and a backrest to ensure your guitar doesn’t scratch. This guitar stand can fold flat, so it is easy to put away and will help your guitar stay safe between playing sessions.

3. Use a Guitar Hanger

Another excellent way to keep your instrument safe is to use a guitar hanger. You can get this Snigjat Guitar Wall Hanger from Amazon.com. They are perfect for keeping any guitar safe and out of the way. These guitar hangers have a unique V-shape bracket, ensuring your guitar is secure and won’t rub against the wall.

Hanging your guitar on a wall hanger exerts the force in a vertical direction, meaning there is no pressure on the neck, protecting it from warping.

This is the ideal solution for somebody who doesn’t want to leave their guitar lying around but also doesn’t want to pack it away in a hardshell case the whole time. A guitar hanger can also add a bit of aesthetic appeal to your space, especially if you have a few guitars hanging on your wall.

4. Maintain Proper Humidity Levels

Maintaining the correct humidity levels in the storage location is the best thing you can do to prevent your guitar’s neck from warping.

Dry air will dry out the wood your guitar is made of, causing it to shrink and warp. If there is a lot of moisture in the air, the wood will swell. The wood that your guitar is made from requires a specific moisture level and temperature for it to stay impact. If the temperature or humidity fluctuate drastically, they can cause severe structural damages to your guitar.

The ideal humidity and temperature levels for most guitars are:

  • The perfect humidity level is between 45% and 55% (relative humidity).
  • The ideal temperature to keep your guitar in is between 65°F and 75°F (18°C and 24°C).

To ensure that humidity levels aren’t too high or low, you can use a digital hygrometer. Keeping track of the moisture content in the air surrounding the instrument can help prevent your guitar’s neck from warping.

You can get this D’Addario Humidity And Temperature Sensor from Amazon.com. It can fit inside your guitar case and read both the humidity and temperature inside the case. It’s accurate and has a memory feature so you can keep track of the temperature and humidity fluctuations your guitar has been exposed to.
