Using it on the ribbon T-bone RB500 (which is an awesome microphone) to prevent 48V on this mic :) It sounds ok for the price. Using this device, you need less pre-amp gain, which is good if your pre-amp is noisy.

Does the job perfectly, needs more recognition
Ronfontu 25.01.2021
Little disclaimer: I would have gone for the Klark Teknik CT1 if it were in stock but I needed an preamp asap.

This preamp does a good job and needs more recognition imo.
There is not much to say, go for it if you want to save money and avoid overpriced stuff. I used this with the Rode Podmic (I have 2 of each) and it let me put my gain way lower, reducing ambient noise. On the two FetAmps I have bought, one is a little bit loose when plugging it into the mic, that's why I gave it 4 stars. Other than that, I didn't have any problem. I would recommend this item.

Simple and elegant solution to adding gain
Audio geek 09.05.2021
These FetAmps were bundled with the new SM7B microphones we purchased for a studio rebuild. They do exactly what they say on the tin and give the 7B a much needed boost. For some reason though when used with our Alice Series A desk we get a very low level buzz induced to the signal chain and this affects all three FetAmps and channels in any combination. If I try them all on another mixer (D&R Airmate) the buzz disappears altogether and the gain improvement is crystal clear so I can only attribute the issue to the Alice desk itself. Luckily the Alice has a good 60dB of adjustable gain and these channel are superbly quiet so we weren't in trouble. I still need to experiment further with another Alice Series A in the second studio and probably just need to add some decoupling to the channel strip to soft this buzzing issue. After all they are classic mixers and need a bit of TLC from time to time!

A must for SM7-B owners - Just works
GarethOB 27.09.2021
A simple little device that boosts the notoriously low output of the SM7-B very transparently, and doesn't need expensive preamps to boost it. The quality is a little flimsy (any of the others of tried are flimsy too), but if you're careful with it, it's a great buy
