This Electro-Voice Cardine II, Model 731 studio microphone is in very good condition. I inherited it from my dad who was Assistant Chief Engineer for the Stromberg-Carlson Sound Division for many years. The microphone comes complete with an unused mating 3-pin connector and the original Electro-Voice Model 345 external shock mount. The rare shock mount is as resilient as ever, a tribute to excellent material selection and the fact that is has been stored in a cool dry... environment for most of it's life. The microphone has been tested and works fine. Although I have no way to verify its sensitivity or frequency response, it sounds great.
