Thank you for your answer. I’ve applied the modification you told me about and now the signal gets through the pedal when it’s bypassed, still not getting anything when the pedal is activated, though. What could it be?
Thank you very much!
P.S. – Here is the current state of the build (without wilikie1’s modification): https://drive.google.com/open?id=10–JyWKFaVbNonoZM-rwUxlBkdzQ-jR4
