never heard of them... that said, it looked like he was using a wireless mic, is there a capacitor in there that could zap him??? never heard of them... that said, it looked like he was using a wireless mic, is there a capacitor in there that could zap him???Nothing in a wireless microphone can zap you. However many years ago, when I was somewhat younger, I once helped a band to set up. They had an amazing quantity of cables and electrical boxes, many of which were connected to mostly metal instruments. If the live wire connects to the surface of one instrument, and another remains grounded, the voltage between the two will be sufficient to attract your attention. You can also touch something on the scene that is grounded.
All these cables and speakers and amplifiers and instruments are portable, and they get banged up whenever you set up and tear down. Nobody ever monitors these things with a Megger - not in a true band anyway :-)
