Flat picks, thumb picks and finger picks from Dunlop, Ernie Ball, D'Addario, Herco and Fender, in nylon, cellulose and Ernie Ball's Everlast material, from thin .60 mm nylon up to 2 mm. Dunlop Jazz III and the standard nylon picks are the ones players ask for by name. Thicker picks give more control and a fuller note for lead work; thinner ones are easier for strumming. Buy a few gauges and find out which one you stop noticing.
