Kinetic Fuzz - 470n polarized

[slowpogo]

Building the Kinetic fuzz and didn't catch that C2 (470n) is labeled as polarized on the board and schematic (but not in the parts list, maybe worth a note).

Is the polarized cap totally necessary? or can I sub a 470n film cap?

I bet since it's just dumping to ground and not directly in the audio path, Keeley chose to use a cheaper electrolytic cap there.
Scales of manufacturing, those pennies-per-unit add up.

So, yeah, if all you've got is a 470n Film, you can use it. Might want to grab a handful of smaller electrolytics in your next parts order to cover oddball occasions such as this one.

I'll make sure to update that on the BOM so it's more obvious.

I know listing electrolytic caps in nF can sometimes be confusing but there's usually not enough space on the board to print "0.47u", and ".47u" could be easily mistaken for 47u since the decimal isn't very big.
