This 10" drum head is durable, toneful, and sports Evans' "Dry" format (a series of perforations aound the perimeter of the head) which alleviate unwanted overtones.
EVANS HD (Heavy Duty) Dry batter heads balance durability and sonic response with advanced overtone control provided by precision-drilled dry vents. HD Dry heads are made with a coated outer ply of 5mil film and an inner ply of 7.5mil film, plus a 2mil control ring on the underside of the head and dry vents around the perimeter to eliminate stray overtones. HD Dry heads have a semi-defined attack, with short sustain and a bit less brightness than standard HD heads. This coated head also features Level 360 Technology.
