The Solodallas SVDS Boost recreates one of the earliest full-frequency boost circuits ever used on stage, originally found inside the legendary Schaffer-Vega Diversity System wireless unit. What started as a 1/4” headphone monitoring output soon became a secret weapon for players who discovered it could push their amp harder, delivering up to 30dB of boost with unmistakable vintage colour and harmonic richness.

Unlike a typical clean boost, the SVDS Boost is not designed to simply make your signal louder. It adds the signature SoloDallas “Goalpost” EQ character, enhancing the harmonic detail and the outer edges of the frequency spectrum while keeping the midrange intact. The result is a bigger, richer and more open sound that still feels natural through your existing rig.

With up to 30dB of available boost, the SVDS Boost can be used to drive the front end of an amplifier into classic rock saturation, lift solos, add sustain or bring extra dimension to an already-driven tone. It is especially effective after overdrive, distortion or fuzz pedals, where it can restore low-end fidelity, add thickness and give your gain stages a more dynamic, amp-like response.

The SVDS Boost captures the spirit of the original Schaffer-era stage sound in a compact, easy-to-use pedalboard format. For players chasing vintage rock authority, singing sustain, harmonic complexity and a more three-dimensional boost feel, this is far more than a simple volume lift.

Built with high-quality components and designed for professional reliability, the SVDS Boost is equally at home in the studio, on stage or as a permanent always-on tone enhancer in your pedalboard chain.
