This set of 3 drumheads come in the sizes 10 inch, 12 inch and 16 inch. They are coated to add depth and warmth to the sound which is best for louder music like metal, fusion and R & B. The 2 layers of film provide increased durability and a more controlled sound with fewer overtones. Whether playing casually at home or in a crowd pleasing band, choosing the right drum head can be critical. By Trademark Innovations.
