With the EVANS EMAD2 System Pack, there’s no limit on how you can hone your tone. The included EMAD2 batter and reso heads put your bass drum’s attack, focus and sustain in your hands, allowing you to completely customize your sound. The two-ply construction of the EMAD2 bass batter features one ply of 7-mil film and one ply of 10-mil film, maximizing your attack and low end. The head’s sustain can be dialed in easily, thanks to two interchangeable damping rings. On the other end, the EMAD reso head boasts an offset 4" microphone port in a single ply of 10-mil film, plus a foam damping ring around the port's external edge for greater control of your overtones. Both EMAD heads feature Level 360 technology.
