Flaming woofers, that's better than smashing a guitar anytime.
Handy tip for the day:
Wanna magnetize your screwdriver so you can pick up out of the way screws and such? If you have a big speaker with good sized magnets (there's two) rub it across one a few times and, voila!, magnetized screwdriver. Want it back to normal? Rub it on the other magnet.
