The Groove Pro SNS‑3 snare strainer is a mechanism mounted on a snare drum that allows you to engage or disengage the snare wires and adjust their tension. It typically features a lever or throw‑off action for quick on/off switching, a tension knob or screw for fine adjustment, and mounting hardware compatible with standard shell spacing. This strainer enables the drummer to control snare response, sensitivity, and “buzz” character according to playing style or musical context.
