This isn't really related to the other active discussion right now, so I'm creating a new thread.
My school has a new guitar teacher who set-up a small sound system in one of the classrooms. He has complained that when he is playing his guitar, which is connected to his guitar amp, and he kisses the microphone, he gets a shock.
Now, besides telling him he should step back from the mic, I would love to figure out why. I remember a discussion of this came up a year or two back, but I couldn't find it in the search.
I doubt Phantom Power is on, but I will check that when I get to school and look the system over. I'm also not quite sure what kind of mic he is using, its an SM-58 type, but a cheeper knock-off of it I believe.
I know somehow an electrical connection is being made between his guitar and the mic, but I have no idea how to stop it. Would putting both the amp and the sound system on the same circuit help?
And the system was grounded, because he told me he lifted the grounds, which didn't help. Not that I would expect it to, but he gave it a shot anyway. And yes, I will re-ground the system when I go to help him.
Thanks guys,
Zac
