SSL VHD+ Pre Module

Increase VHD input gain and the Variable Harmonic Drive process introduces either 2nd or 3rd harmonic distortion or a blend of the two to your source material. At lower gain settings it adds gentle valve-style warmth or a touch of transistor edge. As the gain is increased the more extreme the distortion becomes, until at high gain settings it delivers fierce trashy transistoresque grunge. The VHD+ Pre module gives the user ultimate versatility from a studio-grade preamp. Whether it’s ultra-clean traditional SSL, subtle warming, or totally trashy transistor distortion, VHD will change your expectations of what a preamplifier should deliver.
