The Sound Of 1960s London Hits

The Jude & Stereo Jude are authentic reproductions of the original Sound Techniques "A-Range" custom console microphone preamps that helped define the sound of legendary recordings at some of London's most famous studios such as De Lane Lea Studios and Trident Studios. Created in direct partnership between Sound Techniques and Warm Audio, Jude accurately delivers the exact microphone preamp circuit designed by Geoff Frost from those historic London consoles. With original dual-discrete 3035 Class-A amplification, Geoff Frost's proprietary Z-Match impedance circuit, custom-spec CineMag USA transformers, and meticulously hand-wired construction, Jude has the unmistakable depth, punch, and musicality heard on classic recordings by David Bowie, Elton John, Queen, and several Beatles recordings including “Hey Jude”.

Dual-Discrete, Z-Match Magic

Built to original Sound Techniques specifications, every Jude channel preserves the complete signal path and tonal flexibility that made the "A-Range" consoles legendary among engineers and producers. The exclusive 9-position Z-Match control allows each channel to optimize the relationship between microphone and preamp, offering nine distinct tonal interactions that shape gain, transient response, frequency balance, and harmonic character with virtually any microphone. Combined with premium Wima and Nichicon audio-grade capacitors, carbon resistors, custom CineMag USA transformers, and Warm Audio's meticulous hand-tested construction, Jude delivers the authentic British console sound once reserved for a handful of the world's most influential recording studios.
