When looking at photos of top singers, both modern and classic, you will usually see them with a classic Neumann, Telefunken, AKG, Sony or RCA tube or ribbon microphone. Often producers will set aside a studio day for a shoot-out of vocal microphones for a particular singer or track. It’s not uncommon to see a lineup of a Neumann U47, Neumann U67, Telefunken ELAM 251, AKG C12, RCA 44, and any number of other options. The producer and engineer are trying to find the perfect mic to fit the singer’s voice and the track. Many of them have years of experience with particular mics and won’t consider anything but their (or the singer’s) favorite. Luckily, since many of these vintage mics date back to the 1940’s and even earlier, there are several good technicians who are able to maintain and repair them.
