The ideal humidity level for guitars is 45-55%. A humidity level of 70% is too high and can cause damage to your guitar.
Wood is hygroscopic, meaning it absorbs moisture from the air. When the humidity is too high, the wood in a guitar will swell, which can cause a number of problems. The neck may bow, the fretboard may become unstable, and the finish may crack. In extreme cases, the guitar may even warp or delaminate.
If you live in an area with high humidity, it is important to take steps to protect your guitar from damage. Here are a few tips:
- Store your guitar in a case when you are not playing it.
- Place your guitar in a room with a dehumidifier.
- Check the humidity level in your guitar’s case regularly.
- If you live in a very humid area, you may need to have your guitar professionally humidified.
By following these tips, you can help to keep your guitar in good condition and prevent damage caused by high humidity.
Here are some additional things to keep in mind:
- The type of wood used to make the guitar can also affect how it reacts to changes in humidity. For example, rosewood is more susceptible to damage from high humidity than mahogany.
- The age of the guitar can also be a factor. Older guitars may be more resilient to changes in humidity than newer guitars.
- If you are unsure about how to care for your guitar in a humid climate, it is always best to consult with a professional luthier.
