The WA-2MPX is an authentic reproduction of the most revered microphone tube preamp that pioneered the birth of rock 'n' roll and 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, Kurt Cobain, 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-2MPX authentically reproduces all the analog tone of the original to bring vintage warmth and color to your sound.
