Amazing microphone. Two tubes and transformerless. Has a very larger than life, airy sound. It definitely has a great color to it (it’s not a neutral mic). Just serviced from Lauten Audio. They cleaned the capsule, reformed the head basket after a drop, and replaced the power cables to give this baby years of additional life. They were excited to see one of these with such a low serial number. This mic was ultimately discontinued because of the amount of work it took to create a mic so unique.
