Polarised caps in position of non polarised cap

[Sigesmundninja]

Hi, i'm assembling a monster fuzz and i've order som wrong parts. The BOM calls for 0.22uf non polarised caps but i accidently ordered polarised. None of the legs connets to ground so I cant figure out wich way to solder them. Are there any specific rules I could follow here?

Measure the DC voltage on both sides of the circuit where the cap will go (or make an educated guess based on the schematic). The negative side goes to the lowest voltage.
