Remo Dave Weckl Active Drum Dampening System

Controls the amount of ring and resonance of every drum in your kit (except bass drums) with amazing precision. It quickly adjusts for loud or soft playing. Uses a nonrestrictive, free-floating, top-mounted plunger that opens on stick impact. A fully-adjustable stroke control allows you to dial in the amount of desired decay in milliseconds. The device adjusts to any size or style counterhoop (excluding bass drums) and is effective in all playing situations.
