Evans™ snare side clear 500 heads feature a single ply of 5mil film. Something to think about when choosing the other side Evans Ply Evans Drumheads are typically constructed from either one or two plies, or individual sheets, of material. A single-ply drumhead, while less durable than a two-ply head, will respond quickly at a wide range of dynamics and resonate freely. A two-ply drumhead will typically be more durable than a single-ply head. In addition to greater durability, two-ply heads offer an increase in the amount of audible attack and often a shorter sustain. Evans Drumhead Finish The finish of the drumhead is most often thought of purely from an aesthetic point of view, though there are often sonic characteristics that go hand-in-hand with specific finishes. Coated or Frosted finishes are said to add warmth to the tone of the heads, whereas uncoated heads tend to have more definition or attack. Coated batter heads also offer a texture that is ideal for brushes. Though most people use clear reso-side (bottom side) heads, the use of a head with some form of coating will further reduce overtones and result in a warmer sound.
