Boss CE-2 clone not working

Hello Guys!

I'm building a Boss CE-2 clone from matsumin. I was taking my measurements with a 200mV Peak to peak 1 kHz SIN signal. I got a MN3207 and MN3102 from das musikding.

I have verified that the TL022 is putting out the correct signal and responds to the potentimeters, picture attached
I have verified that the MN3207 is reciving an input signal, and it recives a square wave at pin 2 and pin 6, picture attached

I have probed around different places, according to other builders mistakes from different forums, but I just can't wrap my head around the problem I'm facing.. I have attached these pictures.

I get no dry signal at all, and I only hear a faint 1KHz signal when I set the input voltage to 2V.

Thank you all in advance!!
