I have this old black finger:

Issue is I have no idea where power and group from battery is supposed to go to
As you can see, someone before me tried to fix it so now there's 2 battery clips (????)
Any help would be appreciated!

It always had 2 battery clips, to provide bi-polar voltage :wink:

This thread should help and I think this unit is the same as yours (there was 2 versions) https://www.freestompboxes.org/viewtopic ... ger#p47642

Thanks so much! I feel like an idiot.
1 question, do you know if each battery connect to the same lug of the switch?
I can't quite tell from the photos
