PLEASE READ - THE RUBBER/PLASTIC PUSH BUTTONS AND KNOBS HAVE BECOME STICKY FOR SOME REASON. NO MATTER HOW MUCH I CLEAN THEM, THE STICKINESS WILL NOT GO AWAY - I HAVE HEARD OF THIS HAPPENING TO OLDER TOOLS AND TOYS - Used and pulled from a working sound/Lighting system - The bottom is missing 1 of it's rubber 'feet' - Nothing major. It is just the feel/touch of the buttons / knobs - The buttons do NOT stick down or anything like that. Be sure to view the video!
