Here's an RCA BK-6B Dynamic Microphone from the 1960's (2 Available at $100 Each). These small microphones were particularly impressive at the time of their release, as they have a nice transformer tucked inside the small body which allows for more output than most lavalier microphones. These were designed to be worn around a reporters neck, but can be held by a clip (included) for modern uses. Sound quality wise, these are bright microphones with surprising character for drums, guitars, vocals, and other sources. If you've been looking for a small microphone that's easy to hide with a surprising sound, one of these BK-6B's is the microphone for you. Both have new cables to XLR installed. Grab one of these small dynamic microphones from the glory days of RCA!
