The Neumann U47 FET — the solid-state successor to the legendary U47 tube mic. Built around the same K47 capsule, voiced for high-SPL sources, and the standard kick-drum mic on more records than any other microphone.
When Telefunken stopped supplying the VF14 tube in 1965, Neumann needed a new flagship large-diaphragm mic. The U47 FET arrived in 1972 with the same K47 capsule but a solid-state FET circuit — same family, completely different voice. The FET could handle 140 dB SPL, making it the kick drum and bass cabinet mic of choice from the 1970s onward. Discontinued in 1986, the FET was reissued by Neumann in 2014 to original spec and remains a standard close-mic for loud sources.
Same dual-diaphragm capsule as the original tube U47. The capsule is what gives both versions their family resemblance — fat low midrange, smooth top.
Solid-state output stage means the FET can handle 140 dB SPL without compression — far higher than any tube mic. That is why it dominates kick drums and bass cabs.
Single pattern, no remote pickup pattern selector. Built for one job — capturing close, loud sources cleanly.
Neumann U47 FET — solid-state successor to the legendary U47 tube. Reissued by Neumann to original spec.
From the original release through current production. Each version has its own character.
Original production from Neumann Berlin. Components vary by year. Most desirable units are early-1970s with original K47 capsules.
Current production from Neumann to original spec. Same K47 capsule, same circuit topology, modern reliability.
Late-production variant with revised circuit. Slightly different output behavior. Less common in studios.
A short list of rooms and records that put the U47 FET on the map.
The kick drum mic on countless rock records cut at Sound City. Standard pairing with the Neve 8028 console.
Hendrix's room ran multiple U47 FETs on bass cabs and kick. Still in regular rotation today.
Tony Bongiovi's room used the FET on bass cabinets and floor toms — a standard mic in the live tracking arsenal.
Vintage King has placed the U47 FET in more rooms than nearly any dealer in the world. Here is what we tell engineers when they call.
Buying decisions get easier when you can hear the difference yourself. Talk to a consultant before you commit.
The FET is the kick mic. There are alternatives, but everyone reaches for it first. Forty years and counting as the standard.
Use case · price range · what we recommend.
Vintage example with K47 capsule. Tonal character varies by year and condition. Best for engineers who want the exact 1970s sound and have the budget.
Current Neumann production. Built to original spec with modern reliability. Best for new commercial rooms and studios that need backup units.
Lightly used reissue units come up regularly through the Sell or Trade desk. Same spec as new at a lower entry point.
