A package that will give your kit some extra punch and projection! The included Attack 1 Ply snare head is noticeably louder than other ordinary single ply heads. Bright, crisp attack, slightly darker sound. Great when you need a little extra projection. The package also includes the 22-inch Orbit, the perfect hybrid of double-ply and single-ply bass drumheads. Comprised of a 10 mil clear Dynaflex film for the top-ply. For the under-ply, Attack uses a 10 mil nebulous white Dynaflex film with calculated sized and placed orbs.
