Here's an MB MCO 30 Condenser Microphone from the 1970's! This microphone has both the 30 (omni) and 31 (cardioid) capsules included. MB was a German manufacturer that later became MBHO, and still makes microphones to this day. This particular microphone was sold by "Unitra Tonsil" which was a Polish Audio company back in the day. Overall this microphone has a bright sound, with a unique texture that works well on acoustic instruments. This one is in near mint condition and includes two capsules, an original cable, pop filter, table stand, and the original case. These microphones run on two 6V batteries (easily assessable still), which are included in the sale. The batteries turn on when the cable is connected, so be sure to disconnect the cable when the microphone is not in use. Grab this unique MB MCO 30 Condenser Microphone!
