Here are two RCA 74-B Ribbon Microphones from the 1950’s! RCA made these 74-B’s as a “junior velocity” introduction into the ribbon market (2 Available at $825 Each). The 74-B was originally intended for PA use and broadcasting, but has become known as a great studio tool for guitar amps and more. If you’re looking for the boomy proximity effect of an RCA 44, these are not what you’re looking for! The 74-B has a built in rolloff in the transformer that was originally designed for better results with public speaking. These ribbons have a magic effect on guitar amps and bring out the warmth and sparkle that you want to hear. These have been serviced with new ribbons and cables, ready for use!
