SOLODALLAS / SCHAFFER REPLICA STORM This is a booster/limiter pedal that recreates the preamp sound of the legendary "Schaffer-Vega Diversity System" wireless system, which AC/DC's Angus Young has loved. It's the Solodallas/The Schaffer Replica Storm, used by Angus Young himself, John Mayer, and other professional musicians, and has become a hot topic. (Please note that we do not offer discounts.) Please consider purchasing this item with the understanding that it is a used item offered by a private seller. (From the manufacturer's description) In producing the complete reproduction circuit of the Schaffer-Vega Diversity System, this "STORM" is the latest evolution. Based on the latest version of the "Schaffer Replica EX Tower," it successfully incorporates the distinctive character into a compact enclosure and a standard 9V center-negative power supply. The circuit is 100% analog and features an analog limiter adopted from the "Schaffer Replica EX Tower." This is a vintage optical opto-isolator, and it was completed by the latest reverse engineering to completely reproduce the original Schaffer-Vega Diversity System TX10 Transmitter of the time. It produces further sustain and is touch-sensitive, creating a loud and rich tone. Of course, it also functions as a powerful preamp and can provide a +31dB clean boost.
