Smooth but sold it later
Frednugent 20.01.2018
(2020 update. I sold this mic a few months after this review because of the high self-noise and uneven sound. Warm Audio is tempting but you should spend that 1000 euros on a more solid microphone. This one sounds nothing like a U47 and a SM7 would do a better job more often that this microphone)

I got this mic knowing that it couldn't sound as good as a vintage U47 but I was hoping for something close. I was pleasently suprised when I tested it. The sounds is smooth and silky when some smart EQ is applied. It is solid and big souding. I would describe it as "modern vintage", In a good way. I tested it directly into my DAW and it sounds better than all my other mics. I tried it to tape and it opened up like a flower. There is a little self noise that I noticed but controllable with some smart gain staging. It took a little while to find the sweet spot for my voice but once I got it everything flowed. It doesnt sound like a 10,000 Euro mic but does sound way better than what it costs. I also tried it a room mic with drums. Souded great. Warm Audio is sort of taking over the world right now. The WA-47 is definately worth a try if you like a U47 with your voice. This one will be with me for a while. I'm loving it.


WA47 exelent choice
Mile Ross 20.10.2020
If you can’t afford a Neumann or more expensive microphone you should look at this as an option. For a long time, I read reviews and analyzed what experts say about WA47. Almost everyone agrees that it is not and will not give color to the sound like the original U47. Almost all reviewers rate it as a top clone very close to the original. So I decided to buy a WA-47.
My review with the equipment I own also bought from Thomann.
Vocals: Patern Cardioid: the frequency response is fantastic (slightly darker than the new modern microphones) and that just gives it warmth and mid-frequencies equal with the whole spectrum of sound. Grade 5
Acoustic instruments: Guitar still, clasic, small piano, and cello. All Patern position, wow that's nice. Even at a longer distance from the instrument with little eq and compression in all patterns it sounds fantastic. Grade 5
Amplifiers: I tested short time, sounds very well but unfortunately I do not have the conditions for this type of recording.
Noise. Reading the reviews of colleagues when they complain I would say the following. Attention should be paid to the resistances in the circuit from the microphone to the card on which the signal is recorded. In my case, the noise does not exist and does not affect the recording.
I recommend this microphone as very good, and I would dare say an excellent purchase


will make you classical guitar shine
Abdulla J. 28.10.2018
it does more than what's expected from a clone at that price point.
3 stars for quality because the grip of shockmount isn't good. fixed with wrapping extra cloth around the mic.
everything else is good.


Beautiful Mic

I've used many Neumann u47s. They all sound a bit different (with the same characteristics) because they're all very old.
At a fraction of the cost this is a superb alternative. It still has the high frequency "shimmer" (harmonic distortion) you get from the original u47 and hopefully in 30-40 years I won't be able to tell the difference between the original and this one.
Another benefit is if you're running a stereo pair, you won't need to try out several before you find 2 that are similar enough!
