Here’s an RCA 77-DX Ribbon Microphone from the 1960’s! The iconic RCA 77-DX was known as “poly-directional” due to its variable directional patterns available via the adjustable acoustic labyrinth on the backside of the microphone. This RCA 77-DX has all original internals however the M/V bass roll-off switch on the bottom of the microphone was removed at some point and has been bypassed. It is set to its full frequency setting, and sounds like any other 77-DX on the M setting. If you don't see yourself needing the roll-off settings, this is a great deal on a classic ribbon microphone. The RCA 77 is a classic ribbon for drums, vocals, guitars, horns, and more. This one has some light to medium imperfections to the body but is in overall great shape with a new ribbon replacement, XLR cable, new grill cloth, and a repair to the yoke. If you've been looking for the classic 77 sound for one of the best deals out there, this is the microphone for you. Grab this 77-DX ribbon microphone from RCA!
