I have a 3U Audio CM1 that buzzes only when the headbasket is a bit "off axis". I know the headbasket usually doesn't move when the mic is assembled, but for whatever reason my CM1's headbasket does shift a bit. When facing left (probably misaligned) there is a buzz when I touch the mic. When facing right the mic works without issue. I also can't open the mic as I should be able to because the bottom nut doesn't rotate. Maybe it was twisted too tightly and the threading was stripped, I don't know. Now the solution would be "Don't turn the mic's headbasket to face left" and that's a good idea. But there's always a chance of doing it accidentally when putting the mic in a shock mount (like on of those spider ones where you have to tighten the bottom) or clip holder. I have a couple questions about this issue so please help me out if you know the answers.
The first is what would cause the headbasket to shift when the mic is assembled? I'm guessing a screw is loose or the notch in the mic body isn't straight or is the wrong size.
The second is this: My theory is that the headbasket shifting is also shifting the capsule mount, turning the caspule and possibly pulling on the ground wire. Could the ground wire shifting cause the buzzing assuming it's a grounding issue? If this is not the issue please give me an idea of what issues can be caused by a shifting headbasket. I'm pretty sure it is being caused by the headbasket as since I've turned it left and right several times and buzzing only occurs when the headbasket is turned to the left.
The third question is if anyone has opened one of these mics with a really hard to turn nut how/were you able to open up the mic?
Now this mic is under warranty and I have contacted Guosheng about the issue. I'm planning to send the mic in for servicing if shipping won't be ridiculously expensive. But please play along and answer my questions on the off chance shipping is astronomical or I get charged or have to pay a ridiculous COD from a private service like UPS or FedEx.
