The BM9 from Extinct Audio is a general purpose bi-directional ribbon microphone, with a symmetric figure-8 pickup pattern. It is designed to be equally at home in front of a guitar amp, above an orchestra, and everywhere in between. It has a deep, rich bottom end particularly when used close to the source, and has a large bass proximity effect. At the top, the response is smooth and detailed, as one expect to would find in a high end vintage ribbon microphone.
