I would first desolder the dc jack wires and measure the lugs, but first, did you have a 1/4” cable plugged in to the input jack? That will complete the circuit and make the led light up.

That is true. But it won't affect whether or not the effect circuit itself works.

I didn't interpret it as an implication--just wanted to clarify that point for all readers.... :mrgreen:

So I am not getting anything other than in input lead to the PCB for the signal tester. It is dead otherwise.

Can you clarify this, please? Where exactly is the last place--both physically and schematically--that you detect signal in the circuit? Here's the schematic:

With regards to the transistors, did you notice that there were 2 different kinds and that the correct one is in q1?
