The Meinl Wave Drum in 22" produces the authentic sound of surf rinsing on the beach. But that's not all: The high-quality steel balls are sealed between two different skins to create two different sounds. On one side there is a natural goatskin, on the other side a synthetic one made of plastic. The different skins allow the player to create sea noise in two different timbres. In the walnut frame there is a closable filling device so that the number of balls in the Meinl Wave Drum can be determined by the user.
