I've noticed that when I am playing notes, my picking hand's pinky is resting on the guitar body bellow the strings (when hitting individual strings), wasnt aware I was doing this until recently. I think its helping to orient my hand to the strings.
I was looking at the Ace of Spades tutorial by Lawrence Katz and it seems that he does this too. It looks like he's even taken some of the finish off the guitar because of it
My question is, is this a bad habit that I should try to stop?
