Best Guitar Humidifiers Review in 2018

You may or may not be aware that humidity can be a guitar's greatest enemy. When a guitar comes face to face with an environment that is either too dry or too damp, its wood can become warped and the instrument can be ruined.Guitar humidifiers work to protect your guitar from the environment and prevent damage to your instrument.

Why Use a Guitar Humidifier

When guitars are being built they are made in a factory that is completely controlled and optimized when it comes to humidity. They are then sent to music stores that also have controlled, ideal environments. But finally, when someone takes that guitar off of the wall and takes it home, that's when the real trouble begins. Our homes are not usually optimized for a guitar's wellbeing.

Leaving your guitar in an extra damp or extra dry environment can cause damage and may cause the wood of the guitar to crack. It can also lead to fret buzzing and other issues.

Best Guitar Humidifiers

Many people fail to give humidity a real thought after buying a guitar, even if they have spent hundreds or thousands of dollars on it. Nevertheless, humidity is a very real concern that you need to be mindful of if you want to keep your guitar in pristine condition and health.

Who Needs a Guitar Humidifier

While a humidifier may not be necessary for all guitarists, there are some people who are going to need one more than others. Guitar humidifiers are especially necessary for solid wood guitars or guitars that have a solid top with laminated sides.

These guitars are especially susceptible to bad weather and dryness issues. They are very susceptible to the humidity of the rooms that they are kept in. A humidifier is a necessity for these solid wood and solid top guitars.

With that in mind, people in some regions will need guitar humidifiers more than others. People who live in dry, desert environments will definitely need a humidifier to keep their guitar secure.

Additionally, if you live in an area that has extremely cold winters and you use a heater during these months, a humidifier will be a necessity for you as well.

How to Choose a Guitar Humidifiers

There are different things that you should look for in a guitar humidifier and some things that will vary. Not all guitar humidifiers are made equally.

There are a few main types of guitar humidifiers that you can choose. The two main types are soundhole humidifiers and guitar case humidifiers.

A sound hole humidifier will cover the guitar's soundhole or sit comfortably under the strings. A guitar case humidifier will sit in the case of your guitar, usually near the headstock.

A room humidifier can also be an option and may be a better choice if you choose to keep your guitar on the wall.

However, it's recommended to not keep your guitar on the wall at all times. The absolute best place to keep your guitar is in a hardshell case.

A sound hole humidifier or a guitar case humidifier will be the better choice for most guitars.

Tips for Using a Guitar Humidifiers

When using a guitar humidifier there are a few things that you'll want to keep in mind to get the best possible benefit. The truth is, you could risk harming your guitar if you don't use the humidifier properly.

Dryness is bad for your guitar, but excessive dampness can be harmful as well. If the guitar humidifier you choose uses a sponge you'll want to make sure it is damp enough to get the job done, but not dripping wet.

If it is dripping wet, the wood of your guitar could be damaged. You likely won't need to dampen the sponge every single day. Usually, every week or so will be fine.

Additionally, you'll want to know your environment and adjust accordingly. Monitor your humidifier closely to make sure that you're keeping everything well maintained.

If you live in a particularly dry environment you may notice that the sponge drys out sooner than expected. Figure out the specific needs of your environment and go from there.

It's also quite possible to potentially use too much water and damage your guitar. Make sure to not make the tube too damp or let it lay flat at the bottom of your instrument.
