The Sennheiser MD 421 was released in 1960 to much acclaim, with a very tight cardioid polar pattern that borders on "supercardioid" at many frequencies and a clear, present sound that was far superior to most dynamic mics of the era.

The MD 421-U models (U-4 and U-5) feature a 3-pin XLR connector and a switchable high-pass filter that goes from "M" for music (full bandwidth) to "S" for speech (low frequencies attenuated). The U-4 model's original clip had a mount threaded for 3/8" stands, while the U-5 was threaded for 5/8" American stands. Being that most examples seen and sold today have replacement clips, this page will show both versions as they are otherwise interchangeable.

About This Listing

Late 1970s, Sennheiser MD421-U5 Dynamic Mic, for parts or repair.  Passes a little bit of signal but it's not great and it's noisy. It just needs a little TLC that I don't have the time for (this involves very carefully removing very small magnetized pieces of metal from the rubber like membrane that surrounds the capsule, which in turn kills the signal from the capsule and limits bass response. I'm not saying that this mic has that particular problem but it could. There’s a full length video and step by step analysis of this repair online) A new capsule costs around $140, it's still a better deal repairing this one and/or replacing the capsule than buying a used one. Selling as is, no returns.
