Description

The WA-MPX is an authentic reproduction of the most revered microphone tube preamp that pioneered the birth of rock ‘n’ roll & radio-ready hits. During the golden-era of tape recording, this style of vintage tube preamp became the signature sound in the signal chain of hit recordings including Elvis Presley, Les Paul, and Bing Crosby – and is a sound that is still pursued by today’s biggest artists. 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

The WA-MPX is based on the 351-style tube preamplifier found in American tape machines that pioneered the birth of rock ‘n’ roll & radio-ready hits.

Power & Versatility For A Wider Range Of Analog Tone

Delivering an impressive 300v of raw power & 90dB 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 & Handwired 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 (80Hz) & Low-Pass (2kHz) Filters to Refine Tone

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