The Vic Firth MB1H Marching Bass Drum Mallets have been field tested and field proven throughout years of collaboration with the world's finest drum and bugle corps. These mallets feature tapered hickory shafts, which shift the weight of the stick towards the hand for improved balance and control. Spherical heads provide a consistent striking surface. The MB1H was designed for 18" - 22" marching bass drums. Super hard felt heads.
