The D'Addario Acoustic Humidity Bundle pairs two best-selling products which are made to ensure your instrument is always properly humidified. The Acoustic Guitar Soundhole Humidifier (GH) makes it easy to humidify your acoustic guitar, hanging safely in the soundhole, releasing moisture slowly and evenly to achieve optimal humidity. The Humidity and Temperature Sensor (HTS), allows you to check the instrument’s humidification, providing highly accurate readings of relative humidity. The HTS also displays temperature and includes a programmable set point, as well as a memory feature that logs the date/time of the highest & lowest temperature/humidity levels. With this humidity bundle, players no longer need to worry about dryness, warping, or damage to their acoustic.
