Optimum shell measurement (O.S.M.)

SONOR implements a slightly narrow outside shell measurement for optimized head contact. This is a SONOR specialty, resulting in excellent tone, better sustain and controlled decay. All shells are formed by only using pressure from the outside in our special moulds.
