I'm looking to buy a Digitech X series chorus effect pedal from music123.com. Now I'm buying from there since they ship internationally and where I live bass effect pedals are very expensive. My question is - do you have to use the special digitech power supply? Or could I go to my local Radioshack and get a power supply to power 4.8Watts unit? I need a 240V power supply you see, so I can't order the one from music123.com. Or could I order it and then use a transformer? What do you technical minded people suggest?
