Authentic Reproduction Of The Most Coveted Mic For Timeless Studio Sound

Timeless Studio Sound

The WA-47 is an authentic reproduction of the most coveted tube condenser microphone, hailed for its timeless studio sound. The WA-47 accurately matches the sonic profile of the prized vintage originals delivering the deep bass, rich midrange, and smooth highs that made it a favorite of legendary recording artists like Frank Sinatra, Johnny Cash, Ella Fitzgerald, Billie Holiday, Elton John and many more.

A Proper Recreation Of A Studio Legend

The WA-47 is designed and built to deliver the most authentic vintage 47-style sound with zero corners cut. Just like the original, the WA-47 circuit allows a lot of low-end and mid detail to come through. While the lows and mids come together to capture all the rich warmth and detail of acoustic instruments, vocals benefit greatly from the smooth and pleasing top end of the WA-47. The coveted and unmistakably vintage sound profile of the WA-47 makes it the perfect choice to create timeless music.

Key Features

Like the original 47-style mic, the WA-47 includes all the features that deliver a complete and professional recording experience.

The WA-47 uses a true reproduction of the K47-style capsule in the original 47 tube mic. Perfect for recordings where vintage vibe is a must.

The custom USA-made AMI transformer drives the bold sound captured by the capsule, delivering the full body, warmth, and richness out of the WA-47 circuit.

The premium 5751 vacuum tube in the WA-47 delivers rich analog tone with exceptionally low gain - ideal for intimate recordings, especially on vocals.

The WA-47 has three key polar patterns - Cardioid, Omni, & Figure-8. Six additional patterns in-between provide ultimate flexibility and versatility for a variety of recording applications.

This capsule captures authentic analog detail across the 20Hz-20kHz frequency response. With just the right peaks where most vocals sit, the capsule inside the WA-47 will quickly make this a favorite mic for vocals and any source where vintage vibe is a must.

AMI USA-MADE Output Transformer

The history of TAB-Funkenwerk (AMI) transformers goes all the way back to the founding of the most sought-after German analog audio innovations. The TAB (AMI) transformer in the WA-47 is American-made and built to exacting standards as designed by Oliver Archut. The sweet sonic character of the WA-47 would not be possible without the amazing, historically-correct transformer supplied by TAB-Funkenwerk.

The premium 5751 vacuum tube in the WA-47 delivers true analog tone with exceptionally low gain and (11dBA) self-noise. Premium polystyrene, WIMA, and Solen French capacitors are used throughout the WA-47 circuit, providing the excellent signal conversion that this circuit demands.

Hand-Tested, Elite Build Quality

The WA-47 is encased in an ultra-durable nickel-plated brass body with an updated headbasket shape adding additional space around the capsule. Every single WA-47 is meticulously hand-inspected at Warm HQ in Austin,TX by real musicians and engineers with a passion for superior sound.

Element of its stitched pattern may matter to some.
Color: Light Grey, Size: Queen (90" x 90"), Color: Light Grey, Size: Queen (90" x 90")
The blanket color was as expected, its fabric I believe will keep you warm, and no material odd scents which is good. Not a flaw, but what might matter to some, at least for me, is that in its stitched pattern it has a repeated section that has loose threading. I noted close up of that in my photos. I can see that element of the blanket being something that may snag on things sometimes over time from items you might set on this bed blanket. Nothing to cut much of a rating on but I wouldn’t of wanted this blanket due to that if I saw that design feature up close beforehand.

Super soft blanket
Color: Polar Blue, Size: Full/Queen (90 in x 90 in), Color: Polar Blue, Size: Full/Queen (90 in x 90 in)
It turned out nicer than I expected, what a surprise. Very light and soft, slightly stretchy. It felt high quality and the color complimented the room perfectly. My mom even wanted to take it to the paint store and find out what color it is so she can paint her room the same color. Great blanket.

Nice blanket
Color: Southern Blues, Size: Full/Queen (90 in x 90 in), Color: Southern Blues, Size: Full/Queen (90 in x 90 in)
This is a really nice blanket. If fits on my bed very well. It went through the laundry really nice and didn’t fade or ripper. Have any strings come undone. I like the very light green color. My pictures aren’t great, but one side is the underneath side, the white and then the light green is the other picture. This is well-made you can see in the picture up close that it’s so really well. All layers are sewn together, so you do not have bunching up when you wash the blanket. It is super soft with a good weight. It’s not super lightweight, but it’s not heavy at all. Overall, I’m very pleased with it and I would recommend.
