These mics are crafted using imported bodies and built around our BFM (Big F’n Microphone) transformer-coupled circuit — a design inspired by the legendary Neumann KM84, reimagined for large-diaphragm capsules.

The compact “102” style is ideal for tight spots, while the TF33 offers a taller, weightier build with a professional feel. Both feature excellent headbaskets compatible with CK12 or K47-style capsules. The TF33 includes an internal pattern switch by default, while the 102 does not — but it can be configured as a dedicated omni mic.

There are no painting options for these mics. The logo and build config are engraved on the body as-is.

Choice of transformers:

Cinemag 5722 – Clean, balanced, and great on anything.
AMI T12 – Adds low-end body and warmth.
3U GZT-84 – Budget-friendly with a smooth tone.
Neutrik – Lo-fi and gritty with a natural high-pass feel.

Each build includes high-quality components throughout, delivering rich tone, vintage-style warmth, and rock-solid performance. Choose from several premium transformer options to shape the sound to your needs, from smooth and balanced to gritty and character-rich.

Hand-built. Artist-tuned. Studio-ready.
