Walnut Brown M1b :
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 M1’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, angel hoops, true hoops etc.
