Low Tide BBD works but doesn't modulate

[inflatablerobot]

Thank you for considering my issue.
I am getting no modulation of the BBD, howeveer I can hear the BBD chorusing when manually turning the Depth knob.
So the BBD passes through audio and the low pass gate functions as expected.
The ATtiny is outputing random voltages on Pin5.
Pin3 of the MCP602 is getting the random voltage from the ATtiny.
Pin1 and Pin2 of the MCP602 have continuity, so it should be buffering in input on Pin3.
The output of the MCP602 on Pin1 is holding at a constant 0.9V.
This is what is baffling me, why is the output of the buffer not moving along with the input?

Any help you might provide would be greatly appreciated.

I am working off the schematic found here

Here are the troubleshooting steps I've taken.
-insure pots isolated from board with capton tape and air gap, not in a enclosure
-insure MCP602 and ATtiny are getting 5v supply from regulator
-confirmed ATtiny is outputing random voltages between 0-5V on pin5 (I can share the code if interested)
-swapped new ATtiny chip, new MCP602 opamp, BBD, and CD4046
-insure continuity between various connections to rule out broken trace(s)

If the thing is chorusing that’s what it’s deposed to do? Turn the skew fully counter clockwise and it becomes more random
