A few months ago I wrote this blog post about the strange things that I had seen inside ribbon microphones. In those cases the ‘strange things’ in question were put in there deliberately by previous owners or techs trying to repair or improve the microphone.
Since then I have come across a couple of microphones which contained even weirder things – insects!
Before modern foams, felted wool was widely used in microphones for shock mounts, wind shields and the like. Unfortunately, moths love this stuff too.
