Evans Black Chrome drum heads are ideal for the Rock/Metal/Progressive drummer who hits hard, plays fast and desires a new, attractive aesthetic with a punchy tone. Featuring a two-ply construction with a ply of 7mil optically clear film over a 7.5mil black film, Evans Black Chrome provides strong durability combined with a sleek mirror-like appearance and a robust tone. The combination of opposing films (two different types and thicknesses) shortens sustain and provides an accentuated mid-to-low frequency response. Evans Level 360 technology is incorporated to extend the level playing surface of the drumhead, 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 collar resolves the age-old dilemma of traditional synthetic heads consistently not fitting the drum shell without using considerable force.
