FetHead Transformer

Preamp with a nickel core transformer

FetHead Transformer is a high quality inline microphone preamplifier. It provides a very warm and thick yet articulate sound for dynamic and ribbon microphones. FetHead Transformer’s desirable character is a really great addition to (interface) preamps which sound rather neutral. A novel class-A FET circuit combined with a custom wound nickel core transformer delivers 28dB of transformer infused gain. 

Podcast and voice recording

Our FetHead Transformer will get you an instant ‘radio’ voice that works wonders on podcasts and voice-overs. After extensive tests and prototyping we came up with a very portable solution to get a stellar sound with just a regular dynamic microphone. Get a produced sound within seconds. 

Transformer color

Many high end studio grade preamps, compressors, equalizers and consoles have something in common. They all have transformers in the signal path. These transformers impart a huge sonic footprint on those designs. Audio transformers affect the sound quality because they are non-linear. They add a little harmonic distortion to the signal which our ears perceive as “warm and thick”.

Protects the microphone

Some older ribbon microphones do not tolerate phantom power. Fethead uses phantom power to power its circuitry, but doesn’t pass phantom power to the microphone, so rest assured your ribbon mics are safe.
