The Schaeffer-Vega Diversity System—an early and very successful wireless system—excelled at the tasks it was designed for. But there was more magic than met the eye. Though designed to sound as transparent as possible, it nonetheless colored the signal in a way that people like Angus Young and Eddie Van Halen found essential.
SoloDallas explored the possibilities of this circuit before in pedals like theSchaeffer Replica, but the new SVDS Boost strips the formula to essentials. Minimalist controls—one knob, that’s it—make this boost no less delicious. I’m not surprised Angus Young was smitten with the original SVDS. An SG and Marshall 18-watt amp sound fantastic naked, but the SVDS Boost has the rare talent for fattening everything without seeming to favor or obscure any frequency band too much. And as zest to the PAF/Marshall style formula, it makes the kind of rowdy, organic, airy, large, and punch-packing Marshall sound you would dream of getting in a studio or hearing on the radio. There are many shades of this basic awesome color in spite of the single knob. Unity gain lives in the earliest third of its range. From there you certainly get more volume, but mostly you bathe in various hues of compressed, saturated, thick, and dynamite growl. You don’t need a Gibson and a Marshall to use it to devastating effect, either. A Telecaster and Vibrolux snap with attitude and whip-crack energy with the SVDS in the line. And with both guitar/amp combos, the SVDS’ wide dynamic responsiveness to volume and tone attenuation assures that things stay cracking when you need more control.
