Exploring limitless possibilities, Tama's result in the wake of countless experimentation came in the form of the hybrid shell: Walnut/Birch. This shell combination brings the superior quality warmth and mid-to-low frequency tone of the increasingly popular and truly unique Walnut, with the well-defined and uncompromisingly solid attack of Birch. This 4-piece shell pack configuration consists of a powerful 22"x16" bass drum with mounted double tom holder quick/efficient set-up and tear-down. Tama successfully applied their trademark engineering with high-tech and efficient drum craftmanship to create a distinctive sounding and highly flexible drum set.
