Oh, mics are still dangerous. I play a lot of restaurants where you get odd hums... one way to "deal" with that is to remove the safety ground on your guitar amp.. of course, there is then a possibility that there is a difference in potential between yourself as grounded through the amp and yourself as grounded through a microphone... you don't need a carbon element or a tube amp to get badly shocked that way. I and a lot of my dirtbag musician friends still will touch a mic before using it.
