Watch the Pentatonic Picking Exercise 4 online guitar lesson by Jeff McErlain from Beginner Blues-Rock Soloing
I want to talk about guitar picks with you. My preference is the Dunlop Jazz III Ultex as I like the size of it, a smaller pick with a sharp point. This is my favorite, but I've gone through many different kinds of picks and I'm assuming I still will too. The kind of pick and thickness of the pick can make a large difference in accuracy and tone. Generally speaking, the thicker the pick, the thicker the tone. Personally I would suggest nothing lighter than a heavy gauge pick for most purposes. Sometimes I'll use medium for such things as funky guitar parts, or acoustic strumming. Other than that, I'm a fan of the Jazz III.
This came about after many years of working on my technique and being inspired by players such as Eric Johnson. I was frustrated that I couldn't play as fast as him - I still can't, but I have gotten much closer once I switched over to that pick. Interestingly enough and not by coincidence, that is the pick Joe Bonamassa uses, he says, picked up from watching Eric Johnson!
