The Pro-Mark DV3 System Blue Medium-Hard Marimba Mallet speaks well in the mid to high range of the marimba, and has a great attack and articulation, characteristic of this series of mallets. The mallet has a latex-wrapped rubber head with a nylon-wool blend yarn tightly wrapped around. It is the optimal Diversity Series mallet to buy for general use! Diversity Series System Blue Mallets As the name implies, the Diversity Series has been designed by The Blue Devils percussion staff to be a diverse line of mallets for indoor or outdoor percussion. The eight mallets in this line were created to cater a variety of players and educators by featuring four graduated vibraphone mallets and four graduated marimba mallets designed for use on synthetic marimbas as well as rosewood! This line is perfect for ensembles seeking clarity, articulation, and a mallet than can hold up to any musical demand while still maintaining a true, fundamental tone from the keyboard.
