Hi. I have recently picked up a Digitech RP 355 from the US and it is presently being sent to me in India. The Power Adapter that comes with in the box has the following readings. Input '120V ~ 60Hz 18W' Output '9V ~ 1.3A' I would like to know will I need a 'step up transformer' for using the Processor in India? If someone has an RP 355 which you've picked up from India, could you please share the Input & Output readings on your adapter?
