Vic Firth SD1 General Round tip. Ideal for orchestral work‚ rock and band. A legendary practice stick. L = 16 3/8" | Dia. = .635" 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.
