If you want to keep your string instrument in full health, then a humidifier and hydrometer can be essential tools. Extreme humidity shifts can warp the wooden build of your instrument and in some cases, can even cause damage, so it's better to be safe than sorry!
Essential Tools: Humidifiers & Hygrometers
A room with a humidity level of around 50% is the ideal place to store your instrument. If the conditions are less than optimal, placing a humidifier in the soundhole of an acoustic guitar can help counter humidity fluctuations and keep your instrument in top condition. Acoustic guitars, acoustic basses and similar string instruments are also more sensitive to shifts in temperature and humidity than electric guitars, for example. Because the interior of an acoustic instrument is left un-sealed by varnish or lacquer, this is where overly hot, cold, damp or dry conditions can start to have an affect. All-solid models and models with a solid soundboard are most at risk, but it can also be a good idea to equip an acoustic guitar with a laminated body with a humidifier.
If you want to keep a close eye on the humidity level, then you can get humidifiers with an integrated hygrometer, which can either be analogue or digital. If you're also looking for a feedback buster then you could get a humidifier system in the form of a feedback buster.
Frequently Asked Questions About Guitar Humidifiers & Hydrometers
What's the best way to store a guitar?
Guitars are happiest when stored standing so that the body is supported or lying on their back. It's also better to keep your guitar in a gig bag or case to limit dust build-up, and if you do use a stand, avoid stands that support the neck at an angle.
Can guitars handle the cold?
Cold air contains less moisture which can cause the wood of a guitar to warp. As long as the temperature doesn't fluctuate too extremely, then your guitar will be fine.
Can guitars handle heat?
Never place an acoustic or electric guitar in direct sunlight or near a radiator. The ideal temperature for any guitar lies between 17°C and 21°C.
Is it OK when a guitar gets wet?
Guitars don't really like water or moisture at all. When stored in a relatively humid room, the wood can expand and break the body joins. In extreme cases, it can even cause the bridge to come loose.
