Innovative Percussion Thomas Burritt Series Marimba Mallets are designed to let you control subtle timbres during a performance, with a minimum of attack sound (even with the harder models).
These mallets are created by attaching a synthetic core to a ramin handle (with a classy walnut stain), loosely wrapped with a very soft yarn.
The TB4 Medium Hard mallets were made for the top three octaves. Its articulation is speedy, but not sharp.
