Here are two Bang and Olufsen BM3 Ribbon Microphones from the 1960’s (2 Available at $425 Each)! The design of the BM3 led to many modern designs including the popular Royer R121. Today, these microphones make nice options for guitar amps and drums. B&O microphones are 50 ohms and need a large amount of gain for quiet sources. If you’ve been looking for a classy looking ribbon that can add warmth to louder sources, this is the microphone for you! These microphones are in great condition and will come with custom cables and clips. They have fresh ribbons and are ready for use! Grab one of these BM3 Ribbon Microphones from Bang and Olufsen!
