An expansion to the best selling series of marimba mallets, the Robert van Sice signature vibraphone series keyboard mallets are a new voice in the category, offering a beautiful lush sound on instrument without the front end attack characteristic of many vibraphone mallet models. Designed for the solo and chamber percussionists, these mallets blend into the ensemble unlike anything else available, allowing the vibraphone player to feel as comfortable in the concert hall as they do on stage at a club.

The M315 is the brightest sound in the range. Its timbre is sharp and exciting and it is also very useful in the highest register of the marimba.
