The ProMark Diversity Series DV5R "System Blue" Marimba Mallet offers unique sonic capabilities. Its rubber core provides tonal warmth with articulate articulation as required for vibraphone performance. Synthetic cord wrap around the head and the sturdy, yet flexible rattan handle create a mallet that's durable enough for even the toughest of shows while still being able to produce the softest pianissimo dynamics. Developed by The Blue Devils percussion staff, this mallet offers a diverse range of options for indoor or outdoor marching percussion.
