I have this old Brown Bullet from a friend whose father used it years ago. It was made in the 1940s so there’s some history and good mojo about it. It worked but it had some issues. I sent it to Greg Heumann at BLOWSMEAWAY PRODUCTIONS for the fix and he checked the element and made a new gasket, added screw-on connecter and his custom volume control, and a new quality cord. He gave this old mic some new life in only a couple of days. He’s awesome to deal with and you should check his website, lots of info. He builds mics for the big-time players and his work is incredible. Watch his video, too.
I hope to do business with him again.
