Ernie Ball Everlast picks feature highly durable Delrin material for a more secure, non-slip surface.
Do you need help choosing?
If your playing style mostly consists of strumming chords, a lighter pick will flex with your playing to make the strumming easier.
If you want maximum slap for aggressive solo lines, a thick pick will give you the power you need.
Some users will go for the 0.88 or 1.0mm thickness for the goldy-locks style middle ground. Try multiple thicknesses until you find what best works with your playing style.
