You can actually see him turn off the magic loop box at the end of "Sweet Child of Mine"--though you can see that he's using loops early on, and, at one point, the loops fall out of synch and out of tune with each other.

Maybe I was wrong and he was looping on the first one too, though it would have been just as easy to do it the way that I explained it. It occurs to me that if he was looping, then either he's not as good as I thought, or I am better than I thought--
