This Yamaha Stage Custom birch drum shell pack is also great for the beginner or the working professional. The staggered diagonal seam allowed Yamaha to build a thin drum shell that will start round and stay round. The low-mass lugs lets the shell vibrate for superb tone and sustain. Yamaha's Air Seal System used for drum shell construction ensures each and every Yamaha drum shell is of uniform thickness and is perfectly round to achieve superior tone quality and durability. Features a beautiful high-gloss lacquer finish. Hardware and cymbals sold separately.
