These are some of the most unique modern brush designs to reach drummers today. Wire drum brushes were first invented in 1913. After 100 years of very little changes to the concept of wire brushes, we and redesigned and revolutionized the entire concept. Rhino incorporate an adjustable polycarbonate rod and a traditional non retractable wire brush. The rod used in the Rhino is heavier and stiffer than that of the Cyclops and there is no bead. When rod is engaged in or impacted in rims or cymbals the sound it very distinct. The larger rod has incredible reflex and therefore its rebound is extremely fast.
