STAR is the flagship of TAMA Drums. It takes the knowledge and research we have cultivated for the Starclassic series to the next level, re-examining every detail to improve shell resonance. Walnut has long been favored by furniture makers for its beauty and durability. As a drum shell material, Walnut's natural EQ tone is praised by the drumming community both on stage and in the studio. The STAR walnut shells project a booming low end with enough cut to be heard in any mix.
