Stam Audio SA-47F


We are proud to introduce the Stam Audio SA-47FET, an exact replica of the vintage Neumann U47 FET microphone. By strictly following the original schematic and using premium components we have managed to recreate the wide dynamic range, detailed sound and huge headroom of the original that has been used as the industry standard for kick drums, bass and vocals by the most respected engineers over the past 40 years.


Since the capsule and transformer represent 90% of the microphone’s tone, we decided to take extra care and use the best components available. After auditioning all combinations of capsules and transformers, we found we could get the closest to the sound of the original 47-Fet, with the Swiss-made Maiku K47 and the US-made Cinemag CM-13101 transformer. The very high sound quality of both these components, along with premium polystyrene and tantalum capacitors, make this microphone ideal for percussion, kick drums, bass and vocals. Like the original, the Stam 47F can capture powerful sounds with fidelity, and no distortion.


Stam Audio Engineering products are about sound quality first and foremost. Every component of every single unit is premium quality and carefully selected to ensure our units match or even surpass the quality of high end boutique-gear.

So when you see the price for the SA-47F your first thought will probably be: “how is this possible?”

We have made the bold decision to bypass distributors and retailers and use the typical 30% margin on quality components. Whilst we inherit a slightly smaller reach without distribution, we conversely can afford to have a large budget for parts, allowing us to build a better product at a better price than any alternative offerings across all of our product range. Better components mean better recordings.


If you’ve used an original vintage u47 before, we’re extremely confident the SA-47 will put a big smile on your face every time you use it.

However, if you’ve never touched the original before, as gear-lovers ourselves we understand that the only way to really know if a piece of gear is for you, is to put it through its paces.That’s why the SA-47F comes with a 30-day money back guarantee. This allows you to get it into your studio and see how it impacts your recordings. If you love it (and we think you will!), great… keep the unit and create amazing music with it. If not, no problems. Just send it back to us and we’ll fully refund your purchase. Don’t worry, whichever way you decide to go we will remain friends.
