Here is some video taken at the Winter NAMM 2013.. Not by me. I know some folks were there, but I don't recognize too many. Muriel Anderson is at about the 9 minute mark. I also recognize the Kruger Brothers at about the 11 minute mark. Lots of tapping and all kinds of odd looking instruments. Sorry that this isn't Chet, but it is about music and to some degree guitars!! The winter is starting to drag, so I'm a bit bored... LOL
