Hello everyone, I have been recently working on my own effect and I noticed how something very specific changed the entire response of the op-amp from nothing to actually working but I don't understand why.

In this schematic, after the low pass filter in the input and the second cap, theres a connection to ½Vcc via a 1M Ohm resistor, and when its connected the amp works like it should but without it it doesn't work at all.
My question is why does that happen?, Whats the logic here?
(also, my simulated "input" is 120mV at 440Hz)
Thanks in advance,
Maor.
