Sennheiser has been producing the MD21 consistently since 1953. This omni dynamic mic is a fantastic, open sounding utility mic. Great for all kinds of sources. These were hugely popular vocal mics in the 50&#8217;s. They are well loved as drum overheads or crotch mics these days, also awesome in a studio on cabinets, and in live use they still excell for brass micing. According to the Sounds Lekker manifesto, these are still really underrated microphones. Built like absolute tanks and sound fantastic for tons of uses.<\/p>\n<p>The &#8220;U&#8221; version was released in the 70&#8217;s as the XLR &#8220;cannon&#8221; plug grew in popularity. The 421-U4, beginning the standard Black 421 design was released around the same time.<\/p>\n<p>This one is in quite nice, but not perfect cosmetic shape. Looks wonderful though, and shows no major (or even medium) damage.<\/p>\n<p>The mic itself has typical 3\/8\u201d euro thread, so it can easily be mounted on a regular mic stand.<\/p>\n<p>The microphone has been cleaned internally and sounds fantastic, ready to rock.<\/p>\n<p>As always, best price and more info on our website.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sennheiser\u2019s long-running omnidirectional dynamic mic.
