The pick I’ve used most over the years is a Fender Heavy, just a regular pick.
Sometimes Extra Heavy, but that basic shape and material.

Given the option I prefer the green Fender Premium Celluloid.

Lately I’ve been using those big graphite picks Jerry Garcia used.
They’re big and dark sounding so nice for the backline gigs and the brighter sounding new amps and speakers.

Sometimes Vpick large lite.
Bare fingers a lot too!
