i believe what you speak of is the contraption called The Beam. I don't really know how it works but its similar to a huge guitar, in the sense that there are a set of strings over some kind of magnetic pick up ( a huge one). mickey uses a metal bar to stir up electro-magnetic fields by touching the strings and moving the bar around. theres some footage of him using it on the closing of winterland DVD. pretty badass sounding instrument if you ask me...
anybody know when they started using it?
is the beast perhaps that huge rack of percussive instruments that was at mickey and billy's disposal during Drumz?
a whole new gameball
