This Mic was built by David Bock for Moon Martin almost two decades ago. I acquired it from Moon's estate when he passed. I was there when it was assembled, in North Hollywood, Moon used to take me over when he bought stuff from David. I have never heard a better sounding mic. I would put this up against the Sony, any vintage Telefunken or Neumann any day of the week. Comes with Shock mount, power supply, and Telefunken Microphone Suitcase.
