Fil “SoloDallas” Olivieri is obsessed with Angus Young's tone for more than 30 years now. He tracked and bought every piece of gear Angus used in order to find that elusive tone of AC/DC's guitar player. One day he read in an interview done by Guitar Player Magazine with Young, about this wireless unit he uses; the Schaffer-Vega wireless system. Fil immediately tracked Ken Schaffer, the inventor of this unit, got two units sent to him, and the rest is history.

SoloDallas built an exact replica of the Schaffer-Vega wireless system. The Schaffer replica units the company offers are state of the art products which are being used by many leading artists out there like Angus Young, Ronnie Wood, Joe Bonamassa and Sting. They are all based on the original one which was used by AC/DC as well as many other famous bands and musicians during 1977-1981.

The TRS delivers a warm, clear and full tone and brings the sound of your signal to the foreground, a clean boost of up to 30db can be reached.
