Here’s a finished MXL 990 that’s been Transformerized with our BFM circuit and a boutique quality CineMag Transformer. This mic is built with a CK12-style edge-terminated capsule.  It can ship with or without the optional internal pattern switch. It is shown here with the optional improved headbasket from mic-parts.  Like all our boards, this one is hand-assembled in the US with point-to-point capsule wiring. The BFM (Big F’n Microphone) board is our take on the Neumann KM-84 circuit adapted for an LDC. It features a very simple signal path with only high-quality, low noise components between the capsule and the transformer. The FET in each mic is individually based for optimal performance. This is the exact opposite of mass-produced.

The mic body is painted matte blue and badged with our logo. It does not come with the MXL case, shockmout or hardmount.

The optional internal pattern switch is accessed by unscrewing the body cylinder.
