SD6 American Custom Swizzle Maple Drumsticks are SD2 drumsticks 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 ten 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.
