Designed in conjunction with Dave Weckl, the Adjustable Bass Drum Dampener provides drummers the ability to adjust the tone and feel on any size bass drum at all tuning ranges. The dampener simply clamps to the bass hoop and can be adjusted around the circumference of the bass drum without interfering with the bass drum pedal and beater. It can be used on the batter or resonant heads and is great for all drumming applications.
