3PDT Charge Pump Board -9V Grounding

[ScreechOwl]

Hi all, I'm using the 3PDT Charge pump board for a PNP tonebender build. I know to run -9V from the fixed pad, but I'm just realizing I'm not sure where to ground the board. I might be overthinking it, but any guidance would be very much appreciated!

I assume all the ground points on that board are common. Perhaps you could dbl-check that with a DMM while waiting for PedalPCB/Robert to chime in. (?)

That's correct, all of the ground (indicated GND or -) points are common so you can use them how ever necessary for your project.

The most likely spot would be the - output pad (shown in green).
