The WA-47F is a faithful recreation of a high-SPL, low-noise classic celebrated as a 'secret weapon' across world-class studios. The original '47-style FET was released in 1969 and gained massive popularity inside recording studios for its ability to handle fast transients with exceptional detail. Compared to popular tube microphones, the WA-47F has a more pristine top end and a tighter, more controllable bass response. Famous artists such as Dave Grohl and Daft Punk used the original 47FET on kick drums, inspiring generations of drummers and engineers. For vocals, legends like David Lee Roth and Michael Stipe used the original to create some of the most beloved music of all time. The WA-47F shares the same sonic profile as that original microphone, making the WA-47F a studio workhorse that will quickly become a go-to mic in your locker.

WA-47-B-50v Capsule

The WA-47-B-50v capsule is a true reproduction of the single-backplate K47-style capsule found in the original 47Fet mic. This capsule captures incredible detail across the 20Hz-19kHz frequency response. With a unique gradual climb in the mids and slight scoop in the high end, the capsule inside the WA-47F will quickly make this a favorite mic for any source that demands critical detail and pleasing high end at louder volumes.

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-47F is American-made and built to exacting standards as designed by Oliver Archut. The sweet sonic character of the WA-47F would not be possible without the amazing, historically-correct transformer supplied by TAB-Funkenwerk.

Fairchild Transistors & Premium Capacitors

The WA-47F uses premium Fairchild FETs - the same component found in the most exacting and expensive reissues. The polystyrene and premium WIMA capacitors in the WA-47F provide the excellent signal conversion that this circuit demands.

Authentic Appearance & Elite Build Quality

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