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 TB1 Very Soft mallets are excellent for chorales and anything else in the lowest ranges of a 5-octave marimba. They have virtually no attack and tons of gooey warmth.
