Evans System Blue SST Marching Tenor Drum Head, 13 Inch

The Evans System Blue marching tenor series was developed with the DCI World Championship winning corps the Blue Devils. Featuring a unique film combination and sound control technique, the System Blue series offers enhanced attack, tonal clarity and projection with increased durability and tuning stability. 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 technology resolves the age-old dilemma of traditional synthetic heads consistently not fitting the drum shell without using considerable force. For over 60 years, Evans has been an innovator in drumhead manufacturing and design. As the creator of the first synthetic drumhead and other revolutionary products such as EMAD, Hydraulics, and the UV1 series, Evans drumheads are designed with the intent of solving problems for drummers. Regarded for high quality and consistency all Evans drumheads are and feature Level 360 Technology.
