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, EC snare heads feature a single ply of 14mil film for maximum durability with single-ply sensitivity and feel. Sound Shaping Technology ("SST") rings on the underside reduce unwanted frequencies and enhances attack.
