I accidentally plugged a 9v power adapter with wrong polarity into my superego. I powered the superego with the wrong polarity for circa one minute. There was no smoke or smell but now the device does not work properly any more. It powers on but the effect won’t apply. It’s like the device is bypassed all the time.
I opened the pedal and everything seems fine. Does anybody have a clue what happened and if I could repair the superego?
