Which Type of Guitar Humidifier Should You Choose?
When it comes to buying the best guitar humidifier, you need to know which one will best suit your needs. There are a few different types of humidifiers and based on what your specific needs are, you will need to decide which humidifier works for you. The following are some of the basic and most popular types of humidifiers that you can pick from.
Guitar Room Humidifier
A room humidifier is ideal if you have a very large collection of instruments. It would be best to assign a room for storing all your instruments and installing a humidifier in that room seems to be the most sensible thing to do.
It would be advised to keep the humidity level of the room at 45-55 percent. The temperature should be anywhere between 70 and 75 degrees. A room humidifier also works best in a compact or confined space. So if you can keep the door closed, the humidifier will work even better.
If this is not possible, you can also opt for a household humidifier.
It is important to keep your guitar or any other instrument in its case whenever possible while also maintaining a constant temperature in the room. It is important that the wood is not subjected to constant temperature changes. A room humidifier seems to be a good way to maintain perfect humidity in the room and also maintain an ideal temperature that will not damage your guitar.
Guitar Case Humidifier
A case humidifier is a good way to keep your guitar happy and healthy. If you have only a single instrument, it certainly does not make sense to invest in a whole room humidifier. Room humidifiers are costly and can also be quite tricky to clean. Besides, if you are traveling you need a humidifier that is portable and a room humidifier is certainly not one that can be carried in your pocket. An easy way to solve this problem is to simply invest in a case humidifier.
You will not only be protecting your guitar by keeping it in the case but will also be providing it with the appropriate levels of moisture. Since the guitar case has a smaller volume, it is naturally easier to humidify than the entire room. In times of low or fluctuating humidity, it is best to keep your guitar in the case along with the humidifier, unless, of course, you are using it.
At least 45 percent humidity is optimum for guitars and the longer the guitar is exposed to low levels of humidity, the harder your humidifier will have to work on restoring the balance. Case humidifiers are a great alternative to room humidifiers and are also a lot more economical. You will also save time and money on maintaining the humidifier.
Guitar Sound Hole Humidifier
There is often a debate between a guitar case humidifier and a sound hole humidifier. Which one should you choose? While the former is placed inside the case and it works to create a conducive atmosphere for your guitar to thrive in, the latter is placed in the sound hole and also provides humidification to the guitar from within.
Some experts say this is required as the guitar’s exterior is polished and finished and is less likely to be damaged by the fluctuation of temperature and humidity. But the interior of the guitar is simply unfinished wood and also requires humidification. A sound hole humidifier provides humidification to the interiors of the guitar, exclusively. Often, the sound hole humidifiers are suspended in between strings and do not have clips or clamps that may damage the body of the guitar.
But a big problem is that a sound hole humidifier does nothing for the neck of the guitar, which requires moisture just as much as the interior does. After a day of being used and the stress of pulling and tuning the strings, the neck requires a balance in humidity which will prevent the wood on the neck from warping or cracking under pressure. A sound hole humidifier is unable to provide that.
Besides, if a humidifier leaks by mistake, you would rather it leak into your guitar case, which can be fixed easily, rather than inside your guitar, which is the most vulnerable aspect of your guitar’s construction. For these reasons, most guitar enthusiasts prefer to stick with a case humidifier as it is a safer option.
Top Humidifier = Healthy Guitar
As a guitar owner, it is extremely important for you to invest in a humidifier. It is up to you to choose the best guitar humidifier to suit your needs, but it is important for your guitar to have the right amount of moisture. Especially, in a cold and dry climate, you need a humidifier that maintains optimum moisture and humidity.
The acoustic guitar requires at least a level 45-55 percent of humidity. Without the availability of adequate moisture, the wood of the guitar may start warping and cracking. The neck of the guitar, arguably one of the central aspects of the guitar, will be the first to snap under strain if the climate is too dry.
The humidifiers mentioned above are some of the top-rated in the market today. Depending on the type of guitar you have and the specific type of requirements your guitar has, you can pick any of the humidifiers mentioned above.
Any guitar enthusiast cannot emphasize the importance of a good humidifier enough. So speak to your guitar dealer or take advice from knowledgeable friends and invest in a humidifier that works for your guitar. You can even invest in a thermometer that checks the humidity level of your guitar case so you know you are operating at the appropriate levels.
