Does what it's supposed to do!
Working great and does what it's supposed to do - working well with T bone Ribbon mic
Good product!
Is doing its job.
poorly made
stopped working after a couple of months
Nifty little thing that is handy to have in your toolkit. The design is a bit less fancy compared to the TritonAudio version, but it's very sturdy nonetheless. Simply does what it's supposed to do without any frills.
Buzz Noise
Got this product along with the Shure7B.
It will give you more gain into your microphone for sure but the unit I received introduced a terribly loud buzz noise into my signal. I spent months overlooking this thinking the buzz noise came from either my power rig or other pieces of gear in the chain only to find out its the FETAmp.
Not worth the money or trouble.
Excellent silent pre-amp
Whenever I buy a Ribbon mic, I always get one of these with it because it makes a world of difference in the sound level and therefor the noise floor. You can also use them with dynamic mics to really boost the level. This one is very transparent and won't color the sound.
Not expensive but no quality
It would do the job if you are in a very interference less environment but if you have any electric device near it, don't think about it.
The overall quality is quite poor, I have 2 loose screws already.
You should put in the extra 10/15€ and get a Triton FetHead.
So simple and yet so effective
I bought this little guy to pair alongside a Rode Podmic. I have tested the mic both with and without the FetAmp. This tiny piece works wonders and really amplifies the sound of the Podmic allowing me to use the Mic with my Mixer with little to no gain at all. Does exactly what it says it does.
loose fit for the SM 7B
No real issues, only that it fits the SM 7B (the only gear I tried it with) a bit loose. It clicks, but then keeps wobbly.
Good but pricey.
Using this with a shure sm7b and it does increase the gain without adding the noise you would get from a preamp.
It is cheaper than other items that have the same function but I still feel like it's a little expensive.
