Wiring shown above will disconnect the battery when you remove the jack plug

from the input, and also when a DC plug is inserted.
The Board GND connections don’t all have to directly attach to the board. You

can run a couple of wires from the DC connector, one to the board, another to

the IN jack, then daisy chain that over to the OUT jack.
It doesn’t matter how they all connect, as long as they do.
This circuit is standard, Negative GND. Your power supply should be Tip

Negative / Sleeve Positive. That’s the same as your standard pedals (Boss etc),

and you can safely daisy-chain your supply to this pedal.
