A liquid chamber adds fluctuating overtones, which give you new sounds at every turn of your hands.
The Meinl Fiberglass Liquid Ibo Drum is a twist on Meinl's classic Ibo drum. A sealed metal chamber containing water adds fluctuating ovetones to its fundamentals and is permanently bonded to the rugged fiberglass body. The Fiberglass Liquid Ibo Drum is easy to play and offers lots of tonal variations as you experiment with your technique.
