If there ever was a classic in the microphone world, the U47 may be THE ONE.
The original U47 was created in 1947; the first condenser microphone with switchable polar patterns (cardioid and omnidirectional). It featured the now-famous M7 capsule, VF14 tubes (they were military surplus tubes at the time, and if you can find an original they fetch around $2,000 on the used market), and BV8 output transformers.

The combination of these components created an ultra-smooth, musical, large-yet detailed sound that has remained a classic to this day. It was this model’s musical qualities and open top end that converted many U.S. engineers and musicians, who at the time were primarily using darker sounding ribbon mics.
The Wunder CM7 is a meticulous recreation of the original, featuring the larger style BV8 output transformer used in the early runs of the U47. Later productions utilized a smaller transformer, which created 40Hz roll-off in order to comply with the IRT (German Broadcasting Network) regulations. The larger transformer had a 20 Hz rol-off, and the extended low end is preferred by many.

Mike at Wunder has also devised a way to utilize NOS Telefunken EF14 tubes, which were created in the same factory and are physically identical to the VF14. When you combine all these elements with Wunder’s M7 capsule (handmade in Germany), point-to-point wiring, and the knowhow that comes out of the folks at Wunder Audio, you get a classic sound that is true to the legendary "Large Badge" U47.
