Thanks for the quick reply.
I had never used the original power supply when I bought it new (have used this pedal probably under 20 hours) but the problem was intermittent so I let it slide for a long while.
I just plugged in the PF+ with the original power supply and the blinking begins after a few seconds and persists after a factory restore, persists no matter what I try, so apparently the blinking problem is not related power since it exists across every power supply I’ve tried.
Whatever it is, it’s not working properly. Perhaps it is related to the micro. It would be great to get the blinking to stop. Any suggestions are appreciated. Thanks.
