” In 1975 American inventor Ken Schaffer created the first dependable, beautiful sounding wireless system for electric guitar and bass. Little did he know he was also creating a circuit that would transform the sound of rock and roll. ”

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 GilmourAngus YoungEddie Van HalenJoe 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. 


  • BOOST knob controls our vintage boost circuit capable of generating a whopping +30 db. This analog boost is perfect for making lead parts stand out, adding fullness to the signal going into the front end of your amplifier, or pushing it into oblivion!
  • EQUALIZATION EXPANDER increases the far ends of the guitar's frequency spectrum to produce scooped clarity without sacrificing precious mids. The extended low end bumps crucial low-mid frequencies responsible for giving live instruments punch and making them stand out in the mix. The accentuated treble frequencies on the other end of the spectrum accentuate 2nd and 3rd order harmonics to produce the airy presence often associated with the “Schaffer Sound”.
