The Evans EQ4 bass drum head gives you a warm tone, with pronounced low-end and punch. The 10mil 1-ply EQ4 provides durability and a woody attack that speaks, both live and in the studio. The width of the internal control ring varies in proportion to head diameter, giving control to larger drums and lower tunings with the EQ4.
EVANS EMAD Heavyweight bass drumheads provide superior durability and a compressed attack, plus a wide dynamic range and the ability to hone your tone with EMAD.
Adjust attack and focus easier. Balance your power, punch, and low end. The industry standard EMAD (Externally Mounted Adjustable Damping) system from Evans is for drummers who demand the best.
