Pedal PCB marks the vactrol terminals "K" and "A".... which one is positive???? The last time I thought I knew which was which, my LED was backwards (wouldn't light up when on), so now I have my doubts.

Anode is positive
Kathode is negative

I thought cathode was spelled with a “c”? lol. Thanks for the confirmation. I thought “A” was anode. I appreciate it!!!

Can you imagine the destruction that would occur if we were to include a pair of terminals marked AC?

WHy not call it W for 'West electrode' Wikipedia is cool, I didn't know that https://en.wikipedia.org/wiki/Cathode
If only the world would agree that K is the superior C.
