International use...changing voltage

  • Does anyone know if the amp is set up to be used both in 120v and 220v environments without having to modify the circuitry, or are the units design only to work in the country to which it is shipped? I know the specs include the range, but I had another amp that said the same in the specs, but had to be "hardwired" for one or the other. Any first hand experience with the Spark would be appreciated!
