27 dB of Class A FET gain in a 130mm in-line body

Best for: Podcasters and broadcasters using low-sensitivity dynamic mics who need a slim, transparent gain stage that sits right at the mic body

The FetHead is a phantom-powered inline preamplifier that delivers 27 dB of Class A FET gain with a frequency response of 10 Hz to 100 kHz (+/- 1 dB). It connects via balanced XLR in/out, draws power from standard 24-48V phantom, and measures 130 x 30 mm - small enough to hang off the back of any microphone without cable strain. Input impedance is 22 kohm.

Our take

The FetHead and the Cloudlifter CL-1 compete directly for the same use case, and the choice often comes down to character versus utility. The FetHead's 27 dB gain and 10 Hz - 100 kHz bandwidth give it a slightly extended top end compared to the CL-1, which some users find adds a subtle air to dynamic mics. The slim cylindrical form factor is the real practical advantage - it hangs discreetly off the mic's XLR output without bulk. Like the CL-1, it is useless without 48V phantom power from the downstream device, and single-channel users needing two mics boosted will need two FetHeads.

Pros

Extended 100 kHz frequency response adds air to dynamic mics
Slim cylindrical body sits flush on the mic with no bulk
Transparent Class A gain with a clean noise floor

Cons

Requires 48V phantom power - dead without it
Single channel only
Slightly less gain than Cloudlifter CL-1 (27 dB vs. 25 dB - CL-1 claims up to 25 dB peak)
