Vic Firth Keyboard Mallets combine a variety of materials with several head shapes to address a range of instruments and all dynamic levels. The yarn models are wound with 3 ply nylon yarn that is virtually indestructible yet produces excellent cushioning for a softer sound. The cord models are wrapped with a harder finished material which produces a stronger percussive effect. The unwound models feature hard rubber or super-hard phenolic heads for maxium sound. American Custom® mallets feature birch shafts for rigidity and consistency and are favored by players who prefer extra reach without the added flexibility of rattan. All Custom mallets are 16" long and sold in pairs. For the discriminating orchestral and symphonic band performer, the Orchestral Series offers six mallets designed for xylophone and seven for bells. With an extraordinary amount of sound color possible, these mallets feature rattan handles and are also an outstanding choice for marching band and drum & bugle corps. Designed for the solo marimba performer, these mallets feature a large rubber core wrapped in 100% wool yarn for an enhanced, warm, full bodied sound. Their extra weight offers greater sound volume and projection. Each Vic Firth Signature Series model was conceived through extensive discussion and research with the finest keyboard percussionists from a variety of musical styles. The designs are a reflection of their musical requirements in terms of balance, feel, hardness & tone color. The marching keyboard mallets for xylophone and bells feature a two-step design with rugged plastic handles and fiberglass shafts for maximum response and durability. Corpsmaster® keyboard mallets feature heavy heads wrapped with a synthetic blend cord which provides improved durability and better weather resistance than wool yarn. The marimba mallets are constructed with birch shafts, while the vibe mallets feature rattan shafts.
