Ask Bob: Can Humidifier Moisture Damage Electonics?

Question: Could the moisture emitted from a soundhole-covering humidifier, over time, damage the electronics of the ES or the exposed circuit boards that are part of many pickup amplification systems? Are the electronics coated to prevent rust?

Answer: Paul, only if you over-humidified your guitar. With the normal amount of humidity there will be no damage. That said, don’t use a soundhole-covering device. Let the humidifier condition the entire space inside the guitar case, as the whole guitar needs moisture, not just the interior of the body.
