Can the DPDT foot switch be oriented any way? In the diagram the poles are numbered 1-6, and the pedal doesn’t work for me. I want to make sure I didn’t wire it upside down or backwards. Thank you!

It isn't polarized so as long as the wiring looks like the instructions it should be good. Send us some photos at info@modkitsdiy.com and we can check it and help with troubleshooting.

My signal comes through when the pedal isn’t engaged but when I turn it on nothing comes through. Also I get a reading of 4.5 volts at the the transistors collector but I can’t seem to figure out what the issue is.
