Hello, I bought the microphone yesterday and tested it out and from the beginning it had a consistent interference type sound in the background, even though the microphone sounded OK.
After using it for a few hours it sounds worse now, like the microphone is muffled, sounds like it is underwater, and the crackling is still there. I haven't replaced the 9V battery yet.
Could you help me with some troubleshooting so I can test if the microphone is broken or if there is something I can do to get it working properly again please? I am worried that something has got into the condenser mic and is perhaps blocking the microphone from receiving sound correctly, but I am not sure the best, safest way to clean it.
I can attach a recording so you can see what it sounds like but not sure how I can do that in this post.
Thank you very much
