U-47fet Microphone DIY Body Kit

Build your own U-47FET-style microphone with this premium DIY body kit, designed for builders who want studio-grade sound, authentic character, and the satisfaction of creating a microphone of their own.

This project can be configured your way — from a body kit only to a complete microphone package with PCB, capsule, transformer, and component kit options available directly on this page.

The capsule is the heart of your microphone’s sound. Choose an M7-style capsule for vintage richness or a K47-style capsule for focused presence and detail. Our D7 capsule is hand-assembled in Canada for builders who want premium tone, craftsmanship, and consistency.
