Like the Unwound Series, but bigger and bolder! Longer shafts and heavier cores in the Grandioso Series brings a full sound. As with other Balter product families, development of the Grandioso Series followed the evolution of music. As percussion ensembles began getting larger – and the instruments used within them began to change (marimbas began expanding to 5 octaves) – the added projection of the Grandioso Series became a must-have sound.
