It's hard to believe that the Evans EQ system bass drum heads have been around for over 3 decades. Originally starting out with paired EQ1, EQ2 and EQ3 systems offering revolutionary venting, internal dampening and resonance control - these heads quickly became the go to for the best bass drum sounds imaginable.
Evans EQ4 series features a single ply of 10mil film. A fixed internal overtone control ring focuses the tonal response of the drum. The frosted surface provides a warmer tone.
