This pack contains a Force I clear batter head, a Force II resonant head (either black or white), a single-kick pad, and a black Port Hole.

The Force I is a clear, single-ply, medium-weight bass drumhead. The Full Force drumhead features an acoustically "vented" muffling ring that is tucked into the hoop on the underneath side of the head. The muffling ring has special "tone holes" that allow the ring to move and resonate with the head. This head has a powerful attack with outstanding projection. A free kick pad is included.

The Force II resonant bass drumheads come in video gloss colors that feature the same "vented" muffling ring as the Force I heads. A free Port Hole is included. This gives the drummer the option of placing the hole where desired.
