With premium components, true-to-original circuit design, and tape saturation control, the WA-MPX authentically reproduces all the analog tone of the original to bring vintage warmth & color to your sound.

     

    Authentic Reproduction of The Most Revered Tape-Era Tube Mic Preamp:

    Power & Versatility for A Wider Range of Analog Tone:

    Delivering an impressive 300V of raw power & 90 dB of tube gain, WA-MPX achieves clean gain & powerful volume, that pushes the tubes to saturate just like the most timeless analog gear.

     

    Premium Components & Hand-wired Construction for An Authentic Vintage Experience:

    Hand-assembled with three premium tubes per channel paired with custom-wound true-to-spec USA CineMag transformers, the WA-MPX authentically reproduces all the analog tone of the original.

     

    Selectable, All-Analog Tape Saturation:

    WA-MPX uses discrete analog components that provide compression, saturation, and non-linear frequency response for authentic tape-era reel-to-reel sound at 15IPS.

     

    Hi-Pass (80 Hz) & Low-Pass (2 kHz) Filters to Refine Tone:

    The 2 kHz low-pass filter allows you to further shape and focus your tone, dialing in ultimate midrange warmth & punch. The 80 Hz hi-pass filter helps remove unwanted bass noise from unruly sources.
