Here’s an RCA 77-D Ribbon Microphone from the 1950’s! The RCA 77-D was RCA’s poly-directional design, with an adjustable acoustic labyrinth that allows for different bi-directional, uni-directional, and non-directional settings.  These microphones have a nice full sound on their M setting, with bass roll-off options available on the bottom of the microphone (V1 & V2). These ribbons are versatile and make a nice pairing with drums, guitars, vocals, horns, and more! This 77 has an authentic replaced middle band and Xaudia yoke, otherwise it has all original parts aside from normal service (ribbon replacement, new grill cloth, and a new XLR cable). It has an engraving on the backside of the microphone body, but overall looks good. Grab this RCA 77-D from the glory days of RCA!
