Best Humidifiers for Acoustic Guitars

It doesn’t matter how well crafted your guitar is, it’s still vulnerable to weathering damage. The more expensive your instrument is the more pressing the need to put some cautions into place to help preserve its long life, humidifiers are one way of dealing with climactic wear and tear.

For some people, humidifiers may sound like an unnecessary item, or maybe they are completely unfamiliar with them, especially if they are playing guitar as a hobby or they’re just starting. If you are one of these people, stay with us while we break down various features and rudimentary precautions when using a humidifier.

How does humidity affect your guitar?

Similar to humans, musical instruments also have their desired humidity levels. The most comfortable levels for guitars, particularly acoustic ones, are somewhere between 35% and 50%.

The ideal temperature is approximately 70-75 degrees Fahrenheit range( 21°C -24°C). Electric guitars are less liable to temperature changes, however, their necks might get warped if the humidity is simply too low or too high.

If the ratio in your home stays under 30% for a chronic period, you may start seeing some damage to your prized six-string. The frets might start to buzz and the tone might deteriorate a bit. Also, the bridge on your acoustic might become loosened, and also the body might start cracking. If the humidity drops below 15%, consequential and often irreparable damage might happen.

On the contrary, with overly high humidity, you might see the top of your acoustic swell up and start to bend. In severe cases, the bridge might pop out.

Very high humidity can ruin your guitar as severely as an excessively dry atmosphere. Hence, it is crucial to avoid exposing your guitar to extreme humidity levels.

Isn’t dry air good for a guitar’s tone?

Certain guitarists think that a dry environment will intensify a guitar’s tone, but that is false. While it is true that natural aging causes cell crystallization and hardening of the wood which results in a louder and more dynamic sound it has nothing to do with dryness, which will only cause damage and require structural repairs within the long term.

What Is A Guitar Humidifier?

A guitar humidifier is a device that evenly disperses water vapor within your guitar case, and in most cases actually inside of the guitar itself. They do this in several different ways but essentially they are made of something very absorbent which either comes able to install or needs to be wet.

Some guitar humidifiers use a dampened sponge or other materials with a sponge-like consistency. Certain ones are man-made, but many of them are naturally originated composites. Some use salts or clay and others use more sophisticated composites that have been lab designed to have properties specifically fit for function. These can be in the forms of crystals, beads, or jellies. Some are engineered with materials that have superior absorbency and extra high water retention. Guitar humidifiers have immensely high capabilities for an item so simple.

The porous component is then put in a container to stop the water from touching the instrument itself. Then it can securely create an adequate humid environment inside of your guitar case. Ideally, you want your guitar to be sealed and packed away somewhere as when left on stands there is always a chance it could be knocked over and damaged.

How To Use A Guitar Humidifier?

Humidifiers are pretty simple and straightforward to use, no matter the type. As most customers will pick any device that is easy to use, the majority of competitive brands have designed humidification systems that require very little effort for your benefit.

If your guitar humidifier doesn't come damp then your first step will be dampening it, it is advised you use distilled water to prevent mold and another bacterial build-up inside the humidifier (which can spread to your guitar). This may be as simple as removing (if removable) the sponge to soak it in some water or as tricky as needing a syringe to fill it via an access point.

After filling them you need to put them into their enclosure which is often a breathable fabric pouch or a plastic pod. They usually hang between the strings in the center of your soundhole because it is a prime position to give the most equal dispersion of moisture, however, some sit below or above the strings in the space left to prevent the strings from stretching.

They take very little maintenance, in general, it is really easy to maintain refills if you pay attention.

Humidifier and Guitar Storage Tips

Now that you know why a humidifier is important and what it can offer, let’s take a glance at a few tips and precautions you need to take in order to keep your six-string in a pristine condition.

  • By no means leave your humidifier in direct contact with the instrument – furthermore suspend it from the strings or put it in the case where it is not touching the wood.
  • Monitor the humidity levels in both the room and the guitar case. Cases tend to show different humidity readings as they are isolated systems – especially hardshell models. So, when you check the room, check the case too.
  • Pairing a case or soundhole humidifier with a room humidifier is a brilliant way to keep your guitar in the most pristine condition at all times.
  • Refrain from moving a guitar from hot to cold environments (and vice versa) too rapidly, because it can cause damage and minor cracks on the finish.
  • Keep your guitar in its case anytime it is not in use.
  • When out of its case, keep your guitar away from, heaters, open windows, and air conditioners. It’s also smart to keep it out of direct sunlight for prolonged periods.
  • Store your guitar in your living space, since storing it in sheds or basements can lead to potential damage as a result of humidity and temperature changes.
  • If you have left your guitar in not so ideal conditions (too dry or too wet) for a certain amount of time, bring it to a professional for a damage assessment and a fresh setup.
