The Vic Firth SD12 American custom swizzle drumsticks are a two sided stick featuring an SD1 general tip on one end with a hard, spun felt ball attached to the butt end. Ideal for fast Changes on cymbals. The American custom line consists of a variety of models conceived and engineered by Vic Firth performer and teacher. The first manufacturer to apply the concept of a round striking surface to drumstick design, Vic developed the Other originals that complete the line with jazz players in mind. All models are turned from select rock Maple for a light, fast-playing stick with great Flex and rebound. The Custom line is perfect for the artist who is playing lighter types of music, or prefers a beefier stick without a lot of weight.
