A warm and colorful single-channel tube mic preamp.

The Warm Audio WA-MPX is an authentic reproduction of one of the most revered microphone tube preamps that pioneered the birth of rock 'n' roll & radio-ready hits.

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.
