Feedback loop trouble

Hello!

I attempted to make a feedback loop plug for my Sammich, where the output is split between a female jack and a male TRS connector.


The image corresponds to the wiring, where the square oscillator (output of Sammich) is wired in parallel to the female output connector and pin 3 of a potentiometer.
Pin 1 of the pot is set to ground and the washer pin is wired to the male TRS connector that goes to the Input of the Sammich.
The wiring shows a mono connection but I've made it with a stereo pot so leftOut->leftIn and rightOut->rightIn and the 10k resistor just symbolises the input of the Sammich (no 10k on actual wiring, only for simulation purposes).

 

However, I cannot hear any difference with the pot turned each way, not even when activating the filter in on the patch loaded. 
What am I doing wrong?

Cheers
