I started out in the early '60's with bare thumb and fingers on a nylon-string acoustic--I had a folk teacher, but I wanted to play rock 'n' roll. After I got an electric in '64, and tearing up my fingers on the steel strings (didn't know about light-gauge strings then!), I started using Fender thin picks, and fingers too. I used to break those thins all the time, and one day I discovered thin blue picks called MB's, with a textured grip molded into the rounded edge. I kind of liked the spitty attack I got by picking with the grip end, but they were still too thin to allow for much picking speed. I used Herco mediums for a while in the late '60's, and then at a jam session, someone handed me a nylon rounded 3-corner pick, a JD I think it was, about an .80mm--and I was immediately twice as fast, and the pick sounded a lot like my fingernails. Lesson learned--the right pick makes a huge difference, and what works for someone else may not work for you. I got a big bag of Clayton .88mm nylon rounded triangle picks about 1980, and I'm still using them! And Jim Dunlop (Senior) gave me a bag of those green Tortex rounded-triangles in the mid-'90's--they're good too! On acoustic, I like those rounded-triangle clear V-Picks--gotta get some more of those...
