Evans EC2 Edge Control 10 inch Frosted/Coated Drum Head, B10EC2S Evans 2-ply tom head, the EC2, features an Edge Control ring that isolates and dampens higher overtones, enhances low-end and attack, and enables broader tuning and dynamic ranges. Unlike conventionally damped heads, the EC2 will not choke at higher tuning ranges, or lose its full-bodied presence when tuned low. The unique translucent coating adds additional warmth, focus, and depth.
