Evans 300 Snare Side clear heads feature a single ply of 3-mil film and are designed to provide a wide dynamic range and controlled snare response at all levels. The 300 series is the best-selling of Evans snare side heads. Evans Level 360 technology is incorporated to extend the level playing surface of the drum head, 360 degrees around the drum. The vertically enhanced collar design guarantees even contact with the critical bearing edge of the drum shell, resulting in ease of tuning, extended pitch range and optimum quality of sound. Evans Level 360 technology resolves the age-old dilemma of traditional synthetic heads consistently not fitting the drum shell without using considerable force.
