The four models of the Soloist Series were designed with a simple natural rubber core and yarn wrapping to achieve an “old-fashioned” sound, but without that old-fashioned yarn slap. Similar to the yarn on the Stevens line, there is no “chiff,” slap or contact noise. This results in great dynamic shading ability. Unlike most other marimba mallets, all the models except the SO2s are weighted similarly, so that there is virtually no difference in feel when switching from model to model. All Soloist models are “old-fashioned” single-toned.
