S2 Snareweight M1B = Expressive drum dampening. FLEXIBLE BY DESIGN to match a drummer's natural dynamics. Control the amount of dampening in a snap with 4 different settings... or, flip it up and off the head for none at all!! Patented clip for permanent grip to ALL SIZE metal hoops. Genuine USA Leather. (about 4" across) MAGNETIC flexibility. Nothing "sticks" to your head- keep it open and real. Will never warp, kink or unstick. After years of continuous development with the patented Snareweight #1, 2, 3, and 4, we are now proud to present the Snareweight M1b, the perfect "starter" damper and the newest member of the Snareweight family. The M1b is engineered to control the resonance without sacrificing the brightness of the drum. One M1b has 4 different dampening settings: very light, light, medium damping, to off. Try two M1â€™s on the same drum for more options and control. Remember the M1 fits any size drum;(8",9,10,12,13,14,16,18, etc.) Dampen in a snap or disengage even faster with the on/off feature. Works with triple flange hoops, die cast, s-hoops, angel hoops, true hoops etc."
