The Schaffer Boost - Solo-X is the all-analog boost and equalization expansion circuit from the famed Schaffer-Vega Diversity System wireless used by David Gilmour, Angus Young, Eddie Van Halen, Joe Perry and an endless list of rock gods throughout the 70s and 80s. This unique boost faithfully reproduces the signature "Schaffer Sound" associated with some of the best guitar tones ever produced.
The Solo-X is basically the Storm pedal with only the most essential feature: The Iconic Schaffer Replica sound! The input control (found on the Storm) is internally pre-set on this pedal, and the optical limiter is removed. The Solo-X is left with only the pure boost and same sound of the Schaffer Replica Tower, in a small and easy to use form factor and with an competitive price.
The Solo-X also has an internally adjustable trimmer to pre-set the maximum output boost, so if the pedal is too powerful for you, you can dial back this trimmer to enjoy a wider range on the output boost control.
Emphatic users of SoloDallas effects include legendary guitarists Keith Urban, John Mayer, Joe Perry, Keith Richards, Ron Wood, Steve Stevens, Doug Aldrich, Richard Fortus (GnR), Scott Metzger, Isaiah Sharkey, Chris Stein, Joe Bonamassa, Coco Montoya, Billie Joe Armstrong and Angus Young. Iconic bassists include Pino Palladino, Sting, Rudy Sarzo. Keyboard master Derek Sherinian swears by it on organs and synths too.
