solodallas THE SCHAEFFER REPLICA STORM Guitar effect pedal capable of a wide variety of sounds. Only tested once indoors. Purchased new. Immediate purchase OK. This is the Solodallas/The Schaffer Replica Storm, a booster/limiter that reproduces the preamp sound of the legendary wireless system "Schaffer-Vega Diversity System" used by AC/DC's Angus Young in a pedal size. It has been used by Angus Young himself, John Mayer, and other professional musicians, and has become a hot topic. It adds moderate compression and boost to the amp.
