Hi,
Having some issues with the parametric multi band compressor, there's no sound output when active.
A quick probe of the op-amp packages shows the GND shorted to 9V.

Is there an image of the PCB (rev 1.1) with reference designators hosted anywhere? Trying to trace the circuit without it is agonising.

Thanks

Resistor R22 appears twice on the schematic so the voltage divider resistors were relabeled as R21a and R21b. There is no R12. See the build guide for the schematic.
