Part of the D'Addario family, the global leader in musical instrument accessories, the Evans brand is synonymous with quality and consistency. Decades ago, Evans was the pioneer of drumhead manufacturing and design, and today they are the innovators. The Evans EQ pad is a highly efficient bass drum muffler that attaches to the interior bottom of the bass drum shell with Velcro. The hinged pillow bounces off the drum head, allowing sustain, before returning to damp the vibrating head. It also features a smaller pad on the opposite end which can be used either on smaller drums or for situations where you want less damping.
