Drum Head Evans BD20GB1C for Bass Drum. Evans 20" frosted EQ1 single-ply bass head contains an internal overtone control ring with a removable muffle ring and dry vents to provide a pre-EQ’d sound that is controlled, but cavernous; a white coating provides additional warmth of tone.
Evans EQ1 series features a single ply of 0,254 mm film. A fixed internal overtone control ring can hold a removable EQ muffle ring for additional damping. Dry vents around the perimeter of the drum head offer a focused and articulate sound.
