Just got in a fantastic microphone called the Electro-Voice Model 630 Microphone. The 630 is what they call an omnidirectional dynamic microphone. It is a classic old school microphone dating back to the 1940’s. It has that atomic look of microphones made during those years with cool lines. The 630 was manufactured in Buchanan Michigan. This particular microphone was made from 1940s till about the 1960s.
The company was founded in 1927 by Al Kahn and Lou Burroughs. In 1930 Knute Rockne, the coach for Notre Dame uses one of their new microphones to address the team during practice. Knute refers to the microphone as his “Electric Voice”, a play on the company name. In 1934 Electro Voice developed the hum-bucking coil, which eliminates a hum sound when used around electrical devices. The hum-bucking coil is still used today. In 1940, leading up to the US involvement in WWII, the company introduced a noise cancelling microphone which was used by the military for tank and aircraft communications. After WWII they were awarded a Congressional Citation for their achievement and helping out the war efforts. The company still exists today and that is a testament to how good their products are.
If you’re looking for the Electro Voice Model 630 microphone try using search terms like vintage, retro, atomic, 1950’s, 1960’s and so on. Sometimes people don’t put the actual microphone name and will list it just as an Antique Microphone or Vintage Microphone. Sometimes because of this, you can find great deals on Craigslist, Etsy and Ebay. Good luck.
