Vic Firth SD4 Combo Barrel tip. Light and fast for jazz quartet or chamber music. L = 15 7/8" | Dia. = .545" American Custom® Maple Drumsticks 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.
