Salyers Percussion Makoto Nakura Marimba/Vibraphone Mallets are equally usable on both instruments, made with flexible rattan shafts that allow for vibe mallet dampening techniques. They're all wrapped with yarn, each model in a distinctively different color so you can easily tell which one is which.
These are designed for the uppermost octaves of the instruments and can crawl down towards the middle if you need some intense articulation. The core is much wider on these mallets, wrapped in a vibrant red yarn.
