I've been offered a roland TD-3KW but its american model, I've looked on both the roland UK and US website at the module that comes with the kit and both say it draws the same power: Output Impedance 1.0 k ohms Power Supply AC Adaptor (DC 9V) Current Draw 1,000 mA Accessories I was just wondering will a simple plug adapter be fine or will I need a voltage converter becuase i don't to blow the thing up.
