Fred Kelly’s Flatpicks come in nylon, delrin, or polycarb materials. The nylon material is very durable yet flexible and creates a soft sound on the strings. Delrin is an extremely strong material, and also provides a very soft and natural sound on the strings. Polycarb has an appealing transparent color, and creates a brighter sound than nylon or delrin. These picks have a unique fine textured grip, and the newest Standard Flatpick has a slight ridge around the thumb area to ensure a firm grasp. We also have some new flat picks this year. The Fat Flat Large Pick and The Baby Fat Flat Pick are our latest and greatest! The Fred Kelly Fat Flat Picks only come in the polycarb.
