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. Designed, engineered and manufactured in the USA, the EQ3 Reso bass drum head is a single 7mm resonant head, with an offset 5" microphone port featuring a plastic sleeve which focuses pitch, and an internal overtone control ring. The EQ3 delivers a warm and punchy sound with a controlled, short decay that's ideal for both live and studio applications.
