Acoustic guitar wood needs moisture to play and look its best. A dry guitar can warp, shrink and worse yet, crack. MusicNomad, a leader in equipment-care products, has developed an easy-to-use, no-mess, and low-maintenance guitar humidifier. The Humitar safely releases moisture evenly to eliminate these potential problems. MusicNomad's innovative Humid-i-Bar sponge holds a lot more water than the competition. This means less monitoring on your end while resting assured your fine guitar is being cared for. Need to check the Humitar? It's easy. Just pop the top and touch the insert. If it's wet, leave it. If it's dry, it needs to be rehydrated. To rehydrate the Humitar, simply remove the Humid-i-Bar sponge, soak it in distilled water, and you're back in action.
