The Solid State Logic VHD+ Pre is an incredibly versatile 500 Series mic preamp that delivers ultra-clean SSL SuperAnalogue sound — with a twist. Its all-analog signal path is outfitted with SSL’s Variable Harmonic Drive (VHD) system. As you increase VHD input gain, the VHD circuitry introduces either 2nd or 3rd-order harmonic distortion (or a blend of the two). At lower gain settings, it adds gentle tube-like warmth or a touch of transistor-style edge. As you increase gain, the more extreme the distortion becomes, all the way to trashed-transistor grunge. From pristine clean to full-tilt overdrive, this gives you immense flexibility to forge signature sounds that make your recordings really stand out. At Sweetwater, Solid State Logic gear enjoys Holy Grail status. Audition the VHD+ Pre, and you’ll agree.
