Zildjian Gauge Drumsticks are a series of four models designed to use with all styles of music. The change in size among each 'Gauge' is proportional, allowing a seamless adjustment when using each model. Whether you're in the middle of a gig, or performing in a setting that's quieter or louder, the adjustment time when changing to a different Gauge stick is eliminated. This is due to similarities in taper, length, and tip shape. The familiarity is already there! The 'Fusion' style tip is a hybrid between the popular 'acorn' tip and 'round' tip. It exudes excellent clarity on cymbals, and gives a full sound on drums or percussion instruments at any tuning range.
