Whether you play rock, blues, country or metal, the Evans EMAD2 Clear Bass Drum Head is a true working drummer?s choice. Named for the externally mounted adjustable damping, the versatile system caters to all bass drum tones by allowing each player to control the attack and focus of the drum head by choosing one of two removable foam damping rings. Choosing the thinner foam ring allows for punch and focus without sacrificing resonance, while choosing the wider foam ring maximizes the low end and attack of any bass drum. The 22? drum head has an outer ply of 7mil and an inner ply of 10mil film for added durability. Enhanced with revolutionary Level 360 technology, the clear bass drum head is easier to tune, with a wider tonal range than ever before. Applying the new Level 360 collar shape to the EMAD2 bass drum head allows it to seat itself properly and in turn provides a head that is easy to tune and a sound that is studio ready. Evans EMAD2 clear bass drum heads are available in sizes 18? to 26? with multiple thickness and coating options.
