Evans Onyx EMAD single-ply bass head contains two interchangeable damping rings that maximize attack and low-end without removing the head or reaching inside the drum. Evans EMAD series features a 10mil of single-ply film providing an ideal balance of punch, power and low-end. The unparalleled industry standard Externally Mounted Adjustable Damping (EMAD) system allows the player to adjust attack and focus. The Onyx version is the perfect aesthetic and sonic compliment to the Onyx tom heads and Onyx bass resonant. For over 40 years, Evans has been a pioneer of drum head manufacturing and design. Known for innovative designs such as EMAD, EC2S, and the Hydraulic series, Evans drum heads are made in the USA in a state of the art manufacturing facility. Acquired in 1996 by D'Addario and Company, the global leader in musical instrument accessories, the Evans brand is synonymous with quality and consistency.
