Aion Blueshift (Dimension C clone) problem

[kinokoma]

I recently built a Blueshift and can't get it to work properly. I bought the complete kit from Musikding in Germany. I chose the stock bypass version. When switched on the only effect is that the volume is slightly lowered. Turning the trimpots doesn't change anything.
Unfortunately I don't have an oscilloscope available at the moment. Does anyone have a clue what might be the problem?

There is every chance that the error is in how the switch was wired up.  So go back over each and every connection.  I test my PCBs after they are assembled, before doing switch wiring, to isolate this problem (and see how it sounds in case I want to change anything). 

Then, go over every single part on the PCB, check for bad solder joints, any chip/transistor that may be in backwards...the mistake is usually ours, Kinokoma   

Welcome to the forum!  If you can't find an error by eye after doing it over and over, look here:

Did you ever figure this out? I have the exact same problem!

I link schematic here https://aionfx.com/app/files/docs/blueshift_documentation.pdf for reference,
this is real complex schematic, and it should be drawn indicating what part goes in what PCB, since you have 2 cards...
assuming no error when buiding it, you may focus on:

1) NE570 chips, looking for signal on both their inputs and outputs
2) MNxxxx chip, looking for signal on both their inputs and outputs

then follow signal, I usually go from output back to input according to schematic
