The epitome of vintage vibes and old-school tones

WUNDERLICH is NEOLD, the creators of U2A and WARBLE, at their best - combining rare analog components into a one-of-a-kind piece of vintage gear, meticulously capturing all its analog character in a unique color box plugin that drenches your mixes in vintage vibes and lo-fi textures - not heard since the 1930s.

WUNDERLICH vacuum tube saturation 

WUNDERLICH takes its name from the Arcturus tubes that power the hardware. These ultra-rare blue vacuum tubes were used in professional broadcast equipment in the 1930s. WUNDERLICH vacuum tubes are sought after for their warm, timeless tone. They offer rich, authentic harmonics that merge drive and compression effortlessly.

Analog mojo wherever it's needed

Much more than a name for a gorgeous color box, the sound of WUNDERLICH vacuum tubes runs through the whole unit. They add warmth to the preamp stage, making it perfect for breathing life into vocals. They also help create the smooth flavor and musicality in the Vari-Mu compressor, classic EQ, and onboard mixer. These tubes create special interactions between all these sections, making it all feel so incredibly analog.

A tone marvel

Whether you’re producing genres pioneered with timeless analog equipment, like Motown, adding lo-fi textures and old-school charm to modern styles like rap, or boutique gloss to your mixes - with WUNDERLICH, beautiful things are going to happen.

    A really smooth & warm compressor which seems to breathe life into the signal. Even with very hard compression (which I sometimes like on pianos) it still sounds natural. The smooth EQ (and… Read More

  • Into the mastering chain she goes!

    by Alan Brucke
    Extremely useful as a mixing tool, and equally as useful in mastering. I like to dial in a nice gritty vintage tone and then back the mix off to 15%. In this application, the Wudnerlich tames digital… Read More
