The Warm Audio WA-MPX is an exact replica of the iconic preamp on the AMPEX 351 Tape machine, which was instrumental in the development of rock 'n' roll and radio-ready classics.
The Warm Audio WA-MPX is a single-channel mic preamp with a true-to-original circuit design that provides a precise replication of the original's analogue tone to add vintage warmth and colour to your sound.
During the golden age of tape recording, the original Ampex 351 became a fixture of elite recording studios. This sort of vintage tube preamp established the trademark sound in the signal chain of hit records by Elvis Presley, Kurt Cobain, Les Paul, and Bing Crosby. It's a sound that musicians like The Arctic Monkeys and Mark Ronson are still pursuing today.
