The Dava Grip Tips Nylon Picks feel like having access to multiple gauge thickness plectrums all in one. They have a flexible centre section where the pick is held, grip the pick near the tip and it acts like a heavy gauge for tight picking control, adjusting your grip towards the back of the pick, releasing the centre section gives a light gauge flexible pick for strumming and rhythm playing. These Grip Tips are made from Nylon with a grippy rubber layer over the top for ultimate control.
