Used Guitto GHD-01 Acoustic Guitar Humidifier & Hygrometer Soundhole Moisture System

Year: Current Production

Made In: China

Includes Case/Gig Bag: No

The Guitto GHD-01 is a clever 2-in-1 guitar humidifier and hygrometer designed to help protect acoustic and classical guitars from humidity-related damage. Unlike many soundhole humidifiers that require spreading the strings, the GHD-01 clips directly to the edge of the soundhole for easy installation and removal. The built-in analog hygrometer provides real-time humidity readings, allowing players to monitor conditions inside the guitar while maintaining proper moisture levels.

Designed to help prevent cracking, shrinking, fret sprout, and other issues caused by dry environments, the GHD-01 uses a refillable sponge-based humidification system and requires no batteries for operation. Ideal for players living in climates with significant seasonal humidity changes. The manufacturer recommends maintaining humidity levels between approximately 40% and 70%.
