EVANS EMAD Heavyweight Clear Batter Bass Drum Head 18 in.

The EMAD Heavyweight clear batter bass drum head features two plies of film. The combination of two identical plies of 10-mil film provides maximum durability and a compressed attack while maintaining a wide dynamic range. The EMAD Heavyweight contains two interchangeable damping rings that maximize attack and low end without removing the head or reaching inside the drum. The industry-standard Externally Mounted Adjustable Damping (EMAD) system allows the player to adjust attack and focus.
