Sonitus Acoustics The Kicker 2.0 22"x20" Pillow

This muffling system works wonders. Easy to put in place and stays in place, and gives the drum a rich and deep bass tone without dampening it too much. Absolutely loving it! However, the size is listed as depth x diameter, and not as the more common diameter x depth. My bass drum is 22" diamater x 20" depth, so this was the wrong size for me when I ordered it. I still made it work though, by cutting down the depth by 2" so it fit into my bass drum. As I said, it still does a great job muffling the bass drum! Just make sure you order the right size. :)
