The BP4025 does just fit into a Rycote BBG, but it's easy to press the body too far into the ball so that the head just touches the internal mesh with the obvious consequences! Personally, I find the supplied foam plus additional fur sock (AT BPF-2) a more practical compromise and, with a gloved and steady hand, noise-free recordings can be made. The whole mic can then be stuffed in a jacket pocket when you're done. But I live on a very windy island, and invariably find that a full windshield kit is a better solution, for which my (original) Rode blimp gets pressed into service. So it becomes a fairly bulky solution, but less so than my spaced omni setup in two full windshields plus mounting bar & tripod...
I recently purchased an Audio-Technica BP4025 microphone.
I tried to fit it on a 21mm Rycote BBG Basket Windshield, but it was too tight. The microphone head touches the internal mesh.
I read this while looking for another solution.
I'm going to buy an Audio-Technica BPF-2 Universal Windshield soon and put it into the supplied foam windscreen(AT8172).
Anyway, I would like you to let me know if there is another Windshield that can replace BPF-2.
Also, I wonder if there is a replacement for the AT8172 foam windscreen.
Thanks.
