Say goodbye to the digital audio blues

Whether you need to track pristine vocals, crunched drums or electric guitars on the edge of sonic destruction, the VHD Pre delivers a powerful and versatile sound shaping tool kit - the perfect analogue companion to your digital recording system.

Based on the VHD circuit from our acclaimed Duality console, the VHD Pre adds four SSL mic preamps to any line level DAW audio interface, transforming it into a professional quality, multi-channel analogue recording system.

The four ultra-clean, high-grade mic preamps are combined with independent Variable Harmonic Drive circuits that use 100 percent analogue signal paths to generate rich harmonic distortion - adding SSL analogue attitude to your digital recordings.

As you increase the input gain, the Variable Harmonic Drive circuit introduces a blendable mix of 2nd or 3rd harmonic distortion to your source material, taking it from gentle valve-style warmth through to trashy transistoresque grunge. Its a new world of overdriven possibilities.
