This drum enhancer is an ABS rubber ring designed for drum heads with a mic hole or port. It reduces unwanted ring and resonance while protecting the hole and providing a stable surface for microphones or accessories. The part is white with a black port hole protector insert for contrast and added durability. Key benefits Controlled tone and sustain: Adds targeted damping at the drum head edge to help reduce excessive overtones and uncontrolled sustain without changing stick response. Mic hole protection: The black port hole protector shields the mic hole from wear and prevents fraying around the cutout. Stable mic seating: Provides a consistent, lowprofile surface around the microphone opening to help keep small condenser or dynamic mics steady during use. Durable material: Molded from ABS rubber for impact resistance and long service life in rehearsal and gig settings. Easy to fit and remove: Sits on the drum head around the port hole for quick installation and simple cleaning.
