The Remo Dave Weckl 22" Adjustable Bass Drum Muffling System is designed to give you complete control over the sound of your bass drum. Here are some key features: Design: Developed in conjunction with renowned drummer Dave Weckl. Components: Includes one tube-shaped pillow available in three different sizes, held in place with three adjustable aluminum "C" clamps. Attachment: Clamps attach to the bottom of your bass drum shell with Velcro, allowing for easy adjustments. Functionality: The muffling system doesn't sit on the bearing edge, so it doesn't interfere with tuning or full drumhead vibration. Customization: You can further customize your sound by exploring any combination of bass drumheads Remo offers. This system is perfect for drummers looking to fine-tune their bass drum sound without compromising the drum's natural tone.
