Sandi Rennick is currently the Front Ensemble Arranger for the 9-time DCI World Champion Santa Clara Vanguard. This series of mallets is constructed with smaller, uniquely weighted cores which produce a more focused sound and puts more weight in the players hands. This allows for the sound to speak very quickly and works very well with an amplified keyboard section. The Sandi Rennick Series models are constructed on birch handlewith a matte finish and are wrapped with a synthetic blend yarn durable enough to withstand the environmental conditions of the marching idiom.
