How can I make my snare drum less "ringy?"

Pearl's OM-1 Tone Control clips onto the hoop and features an adjustable pad for partial or total "ring" elimination. "Donut-shaped" mufflers, such as Rem-Os by Remo, Evans E-Rings, and Noble & Cooley Zer-O-Rings and drumheads with built-in muffling such as Pinstripes by Remo, Genera Dry by Evans, and Performance II by Aquarian are also effective.
