Amazingly enough, this simple circuit works quite well. There isn't crosstalk in mine. Not sure if you realize this is using a level shifter for envelope generation, not using a halfwave or full wave rectifier. Maybe there would be crosstalk if it was doing rectification. You are right about the threshold control and bias being tangled together but as I said before, it simply works.

The crosstalk would be from using a dual op amp to buffer the sidechain input, something considered in the first post.
Level shifter, call it how you want, but It morphs into an half wave output at low threshold settings, which is for the best since it means negative peaks can't let the capacitors charge again as much.
I have no doubt the circuit does what it says it does, OP is happy with it and so are others, but we're here to discuss after all.

Final edit: nevermind I got it. It's like the g string 🫥

Trying to figure out the ins and outs gave me a headache 🤣
Ok so supposedly I want to do the 4 cable method, do I simply hookup my cables according to the schematic? The "guitar in" and "to amp in" tips are connected... I'm missing something 🤔

Edit: also, the way I see the pcb, you can't wire a 3pdt for true bypass (?)
