I cannot for the life of me figure out why, but I built a Tonevendor MKII and have no effect signal (using PedalPCB test rig). I have signal in bypass, LED power, and voltages on all transistors appear to be correct. Is there any reason the test rig doesn't work when using charge pumps to switch to positive ground for PNP effects (i/o jack tips aren't at - 9V because of the way the test board circuit is laid out)? I've built a ton of pedals and never had this issue. Super simple circuit, it's driving me nuts. I tried switching out transistors too, no luck there either. No solder bridges, all transistors have the correct pinouts. Any thoughts are appreciated!
