The American Custom line consists of different models conceived and designed by Vic Firth performer and teacher. The first manufacturer to apply the concept of a round and eye-catching surface to a drumstick. Vic developed the other originals for the jazz drummer. All ten models are turned from select rock maple for a light, fast playing stick with plenty of flex and rebound. The Custom line is perfect for the artist who plays lighter forms of music, or who prefers to play with light sticks. The SD12G is actually an SD1 with a felt ball on the back of the stick.
