Frequently Asked Questions
Do I really need a humidifier for my guitars?
Solid wood guitars are sensitive to changes in moisture. When the air is too dry, the wood shrinks, leading to sharp fret ends and potential cracks in the soundboard. Maintaining a consistent environment acts like an insurance policy for your investment.
Will the humidifier ruin my electronics or pedals?
Excess moisture is the enemy of sensitive circuitry. Always position the device at least six feet away from your amplifiers and pedalboard. If you keep your levels within the 45% to 55% range, you should have no issues with your gear.
Can I use tap water in my unit?
Using tap water often leads to a mineral buildup inside the tank. If you have hard water, it is best to use distilled water to ensure your unit stays clean. This simple switch prevents white dust from settling on your guitar finishes.
How do I know if the humidity is actually correct?
Do not rely solely on the built-in sensor of the humidifier, as those can be inaccurate near the water source. Place a separate digital hygrometer on the opposite side of the room. This provides a true reading of the ambient air surrounding your instruments.
Is there a difference between room humidification and case humidification?
Case humidifiers are great for travel or temporary storage. However, a room humidifier is much more effective for a collection of guitars kept on wall hangers or stands. It treats the entire space, ensuring the neck and body stay hydrated simultaneously.
