FetHead
Summary
Abstract
The FetHead (by Triton Audio) is an inline gain booster similar to the Cloudlifter, providing clean gain for dynamic and ribbon microphones via phantom power. It is commonly used with the SM7B and similar low-output dynamic mics. In the community, it is referenced in troubleshooting contexts — notably, it must be physically removed from the signal chain when diagnosing mic problems, and phantom power must be properly engaged for it to function.
Key Characteristics
- Inline gain booster powered by 48V phantom power
- Compact barrel-style form factor
- Provides clean gain for dynamic and ribbon microphones
- Must be physically removed when troubleshooting signal issues
- Less expensive than the Cloudlifter
Use Cases
- SM7B vocal recording with insufficient preamp gain
- Ribbon mic recording where additional clean gain is needed
- Budget alternative to the Cloudlifter
Settings & Sweet Spots
- Insert between mic and preamp via XLR
- Ensure phantom power is engaged on the interface
- When troubleshooting, remove the FetHead entirely — do not just turn off phantom power
Comparable Alternatives
| Product | Price Range | Notes |
|---|---|---|
| Cloudlifter | ~$150 | More widely known, same concept |
| Cathedral Pipes Durham | ~$100 | Another inline booster |
| Shure SM7dB | ~$500 | SM7B with built-in preamp |
Common Mistakes
- Leaving the FetHead in the signal chain while troubleshooting — “Did you unplug the FetHead for the no phantom power test? Doesn’t work if it’s still plugged in”
- Forgetting to engage phantom power
- Not bypassing the FetHead as part of standard troubleshooting when diagnosing mic issues

“Weird issue with an SM7B tonight. Worked previously at their place. Plugged in with good cords, a FetHead that works, and a set of interface preamps that I know work. Mic was hissing heavily.”
