The story behind the rediscovery and reproduction of the circuitry within The Schaffer Replica EX Tower is one filled with intrigue, serendipity, and some of the biggest names in music. It all started in 1976 when American inventor Ken Schaffer developed the first commercially viable wireless unit for guitar and bass, the Schaffer-Vega Diversity System (SVDS).
Though his goal was to protect and restore the integrity of instruments throughout the wireless process, his unique combination of an optical limiter+compressor+expander+EQ enhancement+opamp+line buffer resulted in an enriched signal that miraculously improved the sound of electric guitar and bass.
