I've an old, well loved set of Avantone BSC1 mics, that Busman modded. They've been my goto mics since I bought them in the yardsale last year. Love them.
The brass ring holding the screen in place came loose on an Omni capsule. So I contacted Avantone about a repair.
Next day response, "Give us your address and we'll send you a new capsule, free. No need to return the old one."
Thanks to Glen at Avantone for great customer service.
