Used RCA 77-DX Ribbon Microphone

The RCA 77-DX is a legendary bi-directional ribbon microphone that helped define the sound of broadcast, recording, and film from the 1950s onward. With its unmistakable pill-shaped body, satin chrome finish, and iconic ribbon tone, this mic is both a stunning piece of gear and a work of art. It features a built-in acoustic labyrinth switch that lets you choose between cardioid, figure-8, and omni pickup patterns—pretty advanced for its time.

This mic is a must-have for vintage collectors, ribbon mic enthusiasts, or engineers chasing warm, natural tone on vocals, horns, strings, or anything that needs a classic touch. It's been used by legends like Elvis Presley, Johnny Cash, and countless radio hosts, and it still delivers that smooth, silky sound that ribbons are famous for.
