Here’s a Bang and Olufsen BM4 Ribbon Microphone from the 1960’s! These microphones were ahead of their time and made in Denmark. In general B&O Ribbon Microphones need a good amount of gain and work best oh high SPL sources (guitar amps, drums, etc.)! This one is very clean with a few light signs of rust, with a custom connector to XLR (non-original). These microphones have a velvety tone that makes them a nice option for smoothing out drums and guitar amps. Grab this BM4 ribbon microphone from Bang and Olufsen!
