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, these drum heads are made using two plies of 7mil film, offering consistency and durability for longer playing time. The exclusive Sound Shaping Technology (SST) Edge Control Ring mounted on the underside provides the ideal amount of dampening tailored for each individually sized drum head.
