Evans GMAD Clear Bass Drum Head, 18 Inch

Evans GMAD series features a single ply of 12mil film that delivers increased low end, punch and power when compared to traditional 10-mil single ply heads. The GMAD contains two interchangeable damping rings that maximize attach and low-end without removing the head or reaching inside the drum. Ideal for heavier hitters looking for a solid sound and more life to the head but prefer the feel of a single-ply.
