Designed for durability and projection in marching percussion ensembles, the FE Series contains models for xylophone, marimba, and vibraphone. The skillful blending of rubber, latex, and extra-strong yarn into weighty and articulate mallets makes this series particularly well suited for high-volume performance. FE Birch mallets are made with extra thick (3/8 inch diameter) wax-coated birch shafts for easy grip, increased control, and long life after hours and hours of use.
