I've ordered and received a power supply for my Mic Mechanic 2 as per specifications on all the websites 9v @ 670 ma. It's the TC helicon power plug 9. When I plug it in and turn the switch on, all I get is a blinking red led in the top right corner of the box. What could possibly be going on with this? Am I doing something wrong? Pedal works fine with the aa batteries...help!
