The Superkick I is a clear, 10mil single-ply bass drum head with an added Superkick ring that controls resonance, enhances low-end, and delivers a well-defined, focused attack!Often imitated, never duplicated, the Super Kick line of bass drumheads is an industry best seller and a favorite among those drummers, drum techs and recording engineers who want a musical, controlled bass drum sound without the use of blankets, pillows or external muffling!The patented "Floating Muffling System" uses a narrow band of acoustic felt for a pre-dampened, yet natural sound. The felt moves and "breathes" with the drum head while eliminating unwanted hi-end frequencies and boosting low-end punch!All Superkick models deliver superior bass drum tone control without all the extra work!
