EVANS B12HDD 12 Inch GEN HD DRY CTD DRUM HEAD

Evans Genera HD DRY heads feature two plies of film. An outer ply of 5mil film and an inner ply of 7.5mil film, in combination with a 2mil overtone control ring on the underside that “floats” with the head, eliminating excessive overtones and controlling sustain. Precision-drilled dry vents around the perimeter of head reduce overtones and control sustain.
