The original Schaffer-Vega Diversity System (SVDS) was created by the genius mind of Ken Schaffer in 1975. The landmark wireless system was relied upon for its dependability and beautiful tone by nearly every major touring artist of that era.

The audio circuit of the SVDS caused subtle improvements to the tone of an instrument that caught the attention of some of the greatest guitarists, bassists, and studio engineers of the 70s and 80s. For many it became integral to their signature sound, both live and in the studio.

As used by these legendary bands and players:

AC/DC, Aerosmith, Beach Boys, Black Sabbath, Blondie (Chris Stein), Bob Seger, Bootsy Collins, Clarence Clemons, Boston, Rick Derringer, Electric Light Orchestra, Fleetwood Mac, Foreigner, Frank Zappa, The Grateful Dead (Jerry Garcia/Bob Weir), Heart, Kansas, KISS, Nile Rodgers, Peter Frampton, Peter Gabriel, Pink Floyd (Gilmour/Waters), The Rolling Stones (Richards/Wood/Wyman), Steve Miller, Steven Stills, Steven Van Zandt, Styx, Thin Lizzy, Tom Petty (Mike Campbell), Todd Rundgren, Van Halen (EVH/Mike Anthony), Yes, ZZ Top… and many more.

The Schaffer Replica® (TSR™) is a faithful reproduction of the audio chain of the original Schaffer-Vega Diversity System that has been out of production since the early 80’s. This painstakingly accurate recreation is capable of replicating the elusive tone heard on countless recordings that became known as “The Schaffer Sound.”

The Schaffer Replica® is available in two versions, each an exact rebuild of the SVDS’ fabled audio circuitry:

  • The Schaffer Replica® Tower: replicates the look of the legendary SVDS Model 63EX receiver – ($949 MSRP)
  • TSR™ Pedal: a more affordable pedal version offers all the same functionality and character – ($399 MSRP)
