When I bought my Focusrite bundle, I got a microphone and mic holder. This is what the holder looked like:
The thing is, my old boom stand had a mic slide holder of this type:
So I unscrewed the mic slide from the boom arm:
Then I tried attaching the new holder:
But the ends were the same gender and size. No fit! Oh No! I tweeted and Focusrite told me it fitted most stands. I googled it and there are adaptors I thought I would have to buy. However. I then noticed something too obvious – which is why I over looked it!
which now fits:
The mic holder had a threaded insert! I could have kicked myself for not seeing it straight away. Suddenly it made sense.
A few turns later, and the mic was on the boom, and the threaded insert adaptor was in The Drawer Of Weird Bits And Bobs.
So – user error as usual.
