How to determine cause of guitar hum?

We've been trying to solve a hum problem. We know it's not the guitar (archtop with set in humbucker) because the hum only occurs in one particular place in the room. If we move the guitar even a couple feet away, the hum stops. Discovered that the hum is negligible when using a wood bridge and wood tailpiece. Worse with metal bridge and metal tailpiece.

Serious Humming/Feedback

I recently purchased a brand new Numark Mixdeck Express midi controller. I connected it the other night at a gig to my QSC K12 speakers using XLR cables. On the rear of the controller are 3 XLR outputs that say BALANCED. I connected regular XLR cables (microphone cable) and ran it to the left and right speakers separately. I then tried to power up the speakers and they would not turn on.

My monitors has a hum - resolved ground loop

I wanted to extend my monitors out to another room for a different perspective. So I ran 2 longer cables to the other room, but after hooking them up 1 of the monitors has a hum in it (the other monitor is just fine). I thought it might be something with the 1 cable so I switched the cables to the monitors, but the exact same monitor still hums.

Microphone weird noise / static / hum / helicopter please help :(



I made a account here because I can't find help anywhere else.

I have had microphone problems for about a year.
When I touch computer case the noise isn't so bad but still exits, and when I move microphone in some positions the noise changes little bit. Time to time it was so bad that mic didn't pick my voice at all. Sometimes it was like helicopter...
