Thought I'd throw this out to those who sing while playing? If you use your own mics (I always do) how do you sterilize yours (guards, internal foam)..?? If you use SR provided mics.. how do you ensure theirs are "clean" so you avoid ENT (ear, nose, throat) issues from dirty mics? FWIW - even when SR companies provide sound.. I always use my own mics. I refuse to use theirs, unless I know the company/folks in question.. Thoughts?
