The Custom Pro Series wires are designed with Anti-Choke end plates that significantly reduce annoying snare buzz and also provide a wider range of available snare tension without choking the drum.
The Speed Release straps allow the player to disengage the snare wires without releasing the straps for the strainer or butt clamps. The result is snare wire changes that can happen in seconds. The brass models provide a brighter, resonant sound, whereas the steel models provide a darker, crisp response.
