Innovative Percussion Sandi Rennick IP4002.5 Medium Hard Marimba Mallets were designed to fit right into that 'sweet spot' of front ensemble playing: hard enough to hear all articulations clearly through a drum corps, marching band, or indoor drumline, and soft enough to be usable across the keyboard.
With smaller cores that are weighted unlike any other IP mallets, the Sandi Rennick series mallets produce a focused sound without the immense weight that is typical among front ensemble mallets. Historically, weight was added as the front ensemble grew into its current place in marching bands and drum corps.
With the standardization of amplified keyboards, mallets no longer need to be extra-heavy in order to get the instruments' volume louder. All Sandi Rennick models are made with birch shafts with a matte finish, as well as a synthetic yarn developed to withstand the rugged nature of the marching arts.
