These Wave Drums create the soothing sounds of the surf, with a great new feature: we sealed the little steel balls between two drum heads, one synthetic and the other naturalgoatskin. This means you can choose between two completely different timbres within the Wave Drum. A sealable filling port(see picture) allows you to control the amount of steel balls inside. It even allows you to put extra balls or grains into the drum for a different sound.
