Description : EBD20GMAD The GMAD is a synthesis of the EMAD and G Plus concepts. By utilizing the same exclusive 12mm film to produce the award winning G Plus, the GMAD has greater punch, depth, and durability relative to the original. It is ideal for heavier hitters looking for a solid sound and more life to the head but prefer the feel of a single-ply. Like the original EMAD, the GMAD features an improved version of Evans' patented EMAD, Externally Mounted Adjustable Damping system. A black plastic sleeve holds the player's choice of two foam damping rings of different widths that control attack, low-end, and sustain.
