The Vic Firth Corpsmaster Marching Series M71 hard cord marimba mallets are constructed of durable materials that make them ideal for demanding field performances. Cord wrapped heads offer definition in nearly any octave and are strong enough to stand up to countless hours of playing. Birch handles are rigid but lightweight to decrease fatigue from long practice sessions.
Nice sound, and the shaft feels smoother than most birch, but the heads unraveled within a dozen hours of playing in a high school marching band setting. Don't overestimate the durability.
