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 U47 FET was released in 1969 and gained massive popularity inside recording studios for its ability to handle fast transients and high SPLs. The high SPL handling, especially for a condenser mic, meant that engineers could make kick drums sound huge, and it meant that engineers no longer had to compromise between volume and detail with certain sources.
