Sorry…you were right. I did make sure that the tip and sleeves are correctly installed. Both sleeves go to ground and both tips go in and out of the circuit per the diagram. When first installing, I noticed that one of the black DPDT and the main blue switch were faulty (I learned a long time ago to do a continuity check on these switches…I have been building pedals for over 10 years and know these switches to be faulty). Fortunately, I had good ones on hand. Any way, my pedal is wired exactly to the diagram with the exception of the battery clip which i did not install. The bypass works fine, but the pedal doesn’t work when engaged. I did watch your video and agree with it. But the problem seems somewhere else…what should i do next?
