Fred Kelly's Speed- Pick was designed to be fast on the strings. The long, slim shank allows for precision, speed, and truer tonal clarity. It has a comfortable, yet securely fitting thumbhole, and is available in the delrin material. Delrin is an extremely strong material, and provides a soft and natural sound on the strings. The Speed picks are color coded in Yellow-light, Orange-medium, and White-heavy. Choose gauge (left-handed available in heavy only).
