Best Guitar Humidifier

If you’re a guitar player who lives in a dry climate, chances are you’ll need a guitar humidifier. Like regular humidifiers, an instrument-specific model works to provide moisture to the air inside your guitar. Guitar humidifiers prevent cracking or shrinkage in the wood that could damage your guitar.

Along with a humidity gauge, this is a product that you need to maintain a long life for your guitar.

What Do Guitar Humidifiers Do?

Before purchasing a humidifier for guitars, you should know a little bit about why one is necessary. Because most guitars are made of wood, they require special care and climate control.

If a wooden guitar is stored in an environment with too little moisture in the air, the wood is at risk of cracking or even bursting at the seams. Too much dryness can also affect the bridge of your guitar, causing the bridge to detach from the neck.

The good news is, the problems can be alleviated and often remedied by using a guitar humidifier. And, if you use a humidifier during dry seasons, your guitar will stay properly humidified.

Buying a digital hygrometer is a smart way to test the area around where your guitar is stored. Under perfect conditions, you want the humidity gauge to read a constant 40% or better. That’s the perfect condition to store your guitar without risk of damage.

It would be best if you also were mindful of the temperature. Avoid storing your guitar in an area where the temperature could reach an excess of 80 degrees Fahrenheit.

If you find that there isn’t enough moisture in the area your guitar is usually stored, an acoustic guitar humidifier or an electric guitar should be your next purchase.

Another practice you should be mindful of is storing your guitar in the case when not in use. The guitar case will cut down on moisture loss and also provide a more controlled environment for your guitar humidifier to work.

Do you need a humidifier for your guitar?

You may need a guitar humidifier if:

  • You have an acoustic guitar made of solid wood. Laminate-top guitars do not require humidifiers.
  • You live in a dry, desert area.
  • You have cold winters and heat your home with dry-air heating.

How can you tell if your guitar may be dried out? You’ll need a guitar humidifier if your guitar has these symptoms:

  • The fingerboard shrinks, causing the sharp ends of the frets to extend beyond the edge of the neck.
  • The arch in the top sinks, and so does the bridge.
  • The neck bows forward, requiring a truss rod adjustment.
  • There’s a hump around the 14th fret.
  • Strings buzz at high notes

If your guitar shows any of these symptoms, get a sound hole humidifier into your guitar and put your guitar back in its case. It may take a few days, but the symptoms will likely go away.

What to look for when buying a guitar humidifier?

Beware, some humidifiers are bad for your guitar. Any humidifier that seals the soundhole of your guitar to work tends to do more harm than good.

Usually, those types of humidifiers will add too much moisture to the air. Too much moisture can cause the wood of your guitar to swell. That impairs sound and can damage the guitar’s body beyond repair.

Try to only use a guitar humidifier with a humidity level of 40% or lower to prevent the possibility of too much moisture.

Please stick to the bigger brands, as they’ve got the process down to a science. Dampit and Oasis are the most reputable and known for making the best guitar humidifier products and are also the most likely to work positively for your guitar. The average guitar humidifier will cost you around $14 – $24.

You can find most of these brands at almost any music store, as they’re widely available. But remember, these humidifiers aren’t meant to be used over long periods. If you regularly store your guitar in a dry room, a room guitar humidifier is your best bet.
