OK, so I'm jammin along the other day and looking down at my pedals and something occurs to me I never noticed before... on effects, the "in" is on the right of the box and the "out" line on the left. Living in a world where pretty much everything else goes from left to right (books etc), this is one of the few things I know of that go right to left. Does anybody know why this is? Is it simply so one minimizes the chances of stepping on the cord when standing directly in front of one's pedals? Is there some obscure historical reason why this is so?
