I am considering buying a Shift Line Twin preamp pedal. It is made in Russia and the web site indicates the following: Comes with 220-230V mains Europe socket power adapter (In order to use it in countries with different mains voltage, please ensure you have appropriate power adapter or voltage transformer). Power adapter 12V AC, 750mA. 220-230V primary (for european sockets) adapter included What does this actually mean? Does it mean that I need to purchase a 110 power adapter rated for 12V and 750mA? The web site says "adapter included". I've never dealt with 220v pedals, so any help at all is greatly appreciated. Thanks in advance!
