Preamp with germanium harmonics

FetHead Germanium is high quality in-line microphone preamplifier. It provides a punchy and direct, ‘larger than life’ germanium sound for dynamic and ribbon microphones. Sounding full and rich it is reminiscent of much higher priced vintage gear, making FetHead Ge’s desirable coloration a really great addition to (interface) preamps which sound rather neutral. Our FetHead Germanium utilizes tried and true FET technology combined with a hand selected “New Old Stock” Germanium transistor to deliver 29dB’s of germanium flavored boost.

Germanium Flavor

Germanium transistors were widely used in earliest transistor designs by Neve, EMI, Telefunken, and Fairchild, and have developed a reputation for a decidedly vintage mojo that remains sought after today.

We created a novel hybrid circuit that consists of low noise JFETs and a hand-selected ‘new old stock’ germanium transistor to take full advantage of the “Germanium” sound and at the same time achieve the same sonic quality we are known for. A low impedance output buffer provides output drive to long cables.


Your Fethead Germanium will latch straight onto any XLR equipped microphone, or anywhere else in the signal path between microphone and preamp/mixer.  The electronics are housed in a robust metal chassis with a balanced female XLR input and a balanced male XLR output, rugged enough for use at home, in the studio or on tour.

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.
