Evans BD20GB1 20" EQ1 Batter Drumhead
Warm and round with a full sustain, the 10 mil 1-ply EQ1 utilizes an internal removable EQ muffle ring, a fixed internal overtone control ring, and dry vents to provide a pre-EQ'd sound. The sound is controlled, but cavernous. It's ideal for ambient rock and can open up a drum that sounds too dry with other heads.
