Hi,
I feel dumb. I'm sure this is a minor (and stupid) issue but I can't figure out what's happening...
When I built my first FX pedals I wired all of them with negative sleeve and positive tip, because I have an old wall-wart 9V power supply wired this way.
I've decided a few weeks ago to build a 9V regulated power supply and wired it with negative tip and postive sleeve, because I learned its the common way to do it with FX pedals.
This power supply works perfectly with the build I wired since.
All my board are wired following the off-board wiring schematic found here.
But if I take an older build and just switch power wires inside the box (I swap + and - on the DC power socket) there is a short when I press the footswitch to turn the effect on.
I've spent hours looking inside these pedals to understand... But I don't !
It should be an obvious thing right in front of my eyes that I don't see.
Any idea ?
This is not really a board's debugging, but I don't know where to post it. Sorry if I'm at the wrong place.
