I am just wondering what is the proper way to hold a pick for bass? I've been trying to get better at it and i keep fumbling on the upstroke, I think because of how I hold the pick. I've come up with 3 ways, between my thumb and index finger, between my thumb, index and middle fingers and between my thumb adn the side of my index fingers (sort of a fist shape). The latter seems to be the one I can play the fastest, but I also have to use the most pressure to hold the pick there so I can see my hand cramping up at a show if I play that way. Any suggestions?
