Following in the footsteps of our Birch, Maple, and Beech drum series, Oak shows great promise as a drum shell material. A solid fundamental delivers a powerful sound while its character allows for a unique shell size line up. Beautifully grained, this hardwood creates a drum with stunning looks.
The use of our original Air Seal System is, in part, responsible for the superior quality found in Yamaha drum shells. Select woods are cut into plies, positioned with staggered diagonal seams, and sealed together with evenly distributed air pressure. The resulting shells are perfectly round and of uniform thickness delivering superior tone quality and exceptional durability.
The Oak Custom Series NSD-085A is a 14" x 5.5" snare drum with an all oak shell, low-mass tuning lugs and YESS (Yamaha Enhanced Sustain System) mounts.
