    Product Description

    Here's what Warm Audio say about the WA-47JR Vintage FET Microphone:

    Like Father. Like Son.

    The WA-47jr is an 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 utilizes the same "true '47" k47 style capsule found in our flagship WA-47 tube condenser microphone.  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 an array of other sources.

    Quality components make a better mic.

    The WA-47jr proudly utilizes a custom k47 style capsule reproduction, designed with the same hole pattern and frequency response as the vintage part.  Our version of this capsule (model# WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer with careful precision and repeat-ability.  The WA47jr's low-noise and discrete signal path then paired with an excellent true '47 style capsule allows this mic to obtain a very similar tone to the classic ‘47 microphone at a much lower price tag.  
    Package Includes

    Microphone, Shockmount, Hardmount, Zipper storage pouch.

    3 Polar Patterns

    High Pass Filter

    A -10dB pad switch is available on the WA-47jr.  The pad exists internally within the active circuitry.

    Trusted Customer21st Feb 2020

    Bought the WA-47 JR to record classical guitar at home, so far I'm happy with it. This is my first microphone and I have only completed a few projects, so I'm by no means an expert. I used a Rode NT-1A borrowed from a friend, which seemed very clean, but I prefer this one because it has a bit of a personality. It sounds a little fuller in the lower register. I used it for a recording in a church as well and the space made a massive difference, even though I mostly use the cardioid pattern. Can hear beautiful bell-like sympathetic vibrations, which is really nice. Voices sound particularly nice on it. I think it's a good buy.
