Vater V-FEM40MH Front Ensemble Medium-Hard Marimba MalletVater Front Ensemble Medium Hard Marimba Mallets are made with a blend of synthetic yarn and wool to give you maximum durability and weather resistance while still producing a rounded, full tone on the instrument thanks to their weight. Made with rigid birch shafts, these mallets are very useful for more aggressive passages. They have the articulation needed to hear all of the notes in quick, loud licks without becoming brittle or glassy in sound.
