Recreation of a classic design.

The WA-47jr is a FET transformerless version of the highly renowned classic 47 microphone that has been used on countless hit records for the last 50+ years. The WA-47jr is fully discrete, has 3 polar patterns and is designed for pro studio, home studio, live and broadcast applications. The WA-47jr sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments and other sources.

The WA-47jr uses a custom k47 style capsule reproduction, designed with the same hole pattern and frequency response as the vintage design. This capsule is manufactured by an Australian capsule manufacturer with careful precision and repeatability that defines the tone and signature of the WA-47jr. The WA47jr's low-noise and discrete signal path, when paired with this excellent true 47-style capsule, allows it to obtain a very similar tone to the classic 47 microphone, but at a much lower price tag.

The WA-47jr circuit uses high-quality Toshiba FET’s, Wima film capacitors and Panasonic electrolytic capacitors. The circuit is modernized and simpler than the classic 47 tube microphone, but the components and circuitry are top-notch and have a memorable sound quality.
