Accurate reproduction of the original M49 microphone.
With a 9 pattern switch located on the power supply.
Vintage capture with modern components

Mic features:
34mm K47 type capsule response.
Traditional triode tube circuit typical of the M49C.
We have substituted the soldered in tube for a 7 pin socketed 5654w/6J1. 

An output transformer with the same footprint and turns ratio as the original BV11a used in the M49C.
