The Warm Audio Jude turns one of London's most sought-after console preamp designs into a modern, hand-built piece of studio hardware. Developed in direct partnership with Sound Techniques, Jude faithfully recreates the A-Range microphone preamp circuit designed by Geoff Frost, the same design associated with landmark recordings made at London studios including De Lane Lea and Trident... you know, The Beatles, Queen, Hendrix, and the like. Dual-discrete 3035 Class-A amplification, custom CineMag USA transformers, and carefully selected components give the signal plenty of depth, punch, and harmonic character, bolstered by meticulous hand-wiring and testing to keep the build true to the original design. It's a true piece of British console history, but you don't need a vintage control room to hear what made it special.

The Jude's standout feature is its nine-position Z-Match impedance control, which lets you change the electrical relationship between your microphone and the preamp and explore nine distinct tonal responses. Each adjustment influences transient behavior, frequency balance, gain structure, and harmonic character, giving you another way to find the sweet spot for everything from a condenser to a dynamic or ribbon microphone. Premium Wima and Nichicon capacitors, carbon resistors, and custom CineMag transformers complete the signal path, delivering the musical response and tonal flexibility associated with the original A-Range consoles.
