SoloDallas founder Filippo Olivieri has made it his lifelong mission to replicate the searing crunch tones heard on AC/DC’s 1980 masterpiece Back In Black. SoloDallas’ Schaffer Replica pedal brings back the elusive sound of the 1970s Schaffer-Vega Diversity System used by Angus Young. The Schaffer Replica has now made its way into the hands of players such as Gilby Clarke, Phil X, Elliott Randall and Steve Stevens. Angus Young himself used a Schaffer Replica during the recording of AC/DC's Rock or Bust album!
