The EVANS HD dry coated tom batter drum head rock pack offers durable heads engineered for focused, controlled tones ideal for rock drumming. You get dual-ply film construction with a 5 mm coated outer ply and a 7.5 mm inner ply, plus a 2 mm control ring on the underside to minimize overtones. Precision-drilled dry vents around the perimeter provide advanced overtone control, eliminating stray ringing for a tight, punchy attack. These heads deliver a semi-defined strike with short sustain and slightly reduced brightness compared to standard heads. EVANS Level 360 Technology ensures consistent performance and tone across the entire head surface. Includes 10", 12", and 16" drum heads.
