Evans BD20EMAD 20 Emad Onyx Bass Head - 20 inches

Evans EMAD Onyx Bass Drum Heads are made of a single ply of 10-mil film that creates a pretty balanced punch with moderate attack and focused low-end frequencies. This head is fairly versatile, able to fit right in across a wide range of styles from jazz to metal.

The Externally Mounted Adjustable Damping system - or EMAD - affects how much attack and resonance the head produces without having to remove the head itself. Think of it like a circular pillow.
