Well, I'll be! I am echoing a couple of the comments below, but--still!--I'm really quite astounded about what a difference it makes in sound to rotate the pick by flexing the thumb, to change that axis so that the pick is no longer parallel to the string when it strikes. Wow, what a gorgeous sound, and I had no idea, nor had ever considered it. Thank you so much, Mr. Eldridge. Besides the fact that I have enjoyed, very much, all of the fundamentals lessons (and looking forward to the others) this alone changes everything. Best, David
