The JM17R is a new and improved version of its predecessor, the JM5, and is the most articulate mallet of Jeff Moore’s autograph series. It maintains a pure vibraphone tone while providing maximum attack and articulation. The newly revised design features slightly longer handles and is a little lighter when compared to the original design. This improves mallet balance and feel, while maintaining the enhanced sound and projection that performers have come to expect from the series. Teachers and performers who want improved presence and projection in their front ensemble, while needing a mallet with unbelievable durability need look no further than the Jeff Moore Enhanced Sound Series from Pro-Mark!
