Product description: Star Drums are Tama's flagship series. Since the Star series already has variants made of Bubinga and Maple in its range, the product developers wanted to create another sound option. The choice fell on walnut, a wood with wonderful visual and tonal properties. What is striking are the deep low-end frequencies that give this series a modern sound character.
