Evans REMAD Port Hole Protector for Bass Drum Resonant Head, 4 inch

Inspired by the legendary Evans EMAD system, the REMAD is an external damping device designed for 4 microphone ports in bass drum resonant heads. Applying the REMAD ring to the 4 mic port gives you greater control of your overtones, so you can enhance your pitch, focus, and attack. Every REMAD includes a foam ring that can be applied or removed for additional sound control.
