Hello,
I managed to finish this difficult build : https://aionfx.com/app/files/docs/xenotron_documentation.pdf
It's finally working perfectly, after a huge mistake right at the beginning, with the 3PDT pcb orientation, and some troubleshooting.
There is only one question remaining : is it to be expected that the Loop status led is slightly lighting up in bypass ?

I used a standard 5mm red led for the Loop status indicator, instead of the yellow one mentioned in the instructions.
When i engage the Loop footswitch, the red led is lighting up, but when i disengage the Loop, it remains slightly lit. Not as much as when the Loop is engaged, but there is still a faint red light.
I wonder if it's ok ?
The led connections are a bit unusal for me : a resistor on the negative side (?) and the anode connected to VA. Continuity tests are good, i am not sure how to fix it.
I added a 4k7 resistor on the led + side, but it didn't solve anything.
Every observations and suggestions are welcome !

Thanks for your reply !
Let me give you a quick warning first : You're most probably not going to like it. Please let me explain :
In my bewilderness, confused by an excess of enthousiasm, I accidently soldered the 3PDT daughterboard upside down.
I couldn't see myself unsoldering three 3PDT at once and take the risk to loose everything , so i cowardly decided to keep it that way, and wire the daughter board accordingly.
It might be a little confusing when you'll see this, because all the wiring is reversed.
Let's just remember that the circuit is fully working. Now i will take some pictures and upload them...
I think i found the issue. There was a short between two pads on the daughterboard. Sorry, i should have noticed it before posting...
I'll post the pictures anyway, in case you can still see something suspicious.
