D'Addario GHP Guitar Humidifier Pro

The D’Addario Humidifier Pro is designed to protect your guitar in even the driest conditions. Featuring a specialized hydrophilic sponge that retains up to 12 times its dry weight in water, this humidifier offers longer intervals between refills and superior moisture control for arid environments.

Suspended safely between the strings, the Humidifier Pro releases moisture slowly and evenly inside your guitar without ever touching the instrument’s body. The built-in stopper allows for a quick check of the sponge’s condition and seals tightly when in place. Maintaining optimal humidity has never been easier—just moisten the sponge when it dries out.

• Specialized hydrophilic sponge holds 12x its dry weight in water
• Provides longer protection between refills

• Stopper allows quick sponge status checks without removal
