Abyss 9V-18V

I just built the PedalPCB Abyss (EQD The Depths). I only have one more slot left on my power supply. It runs 18V. I know the EQD Depths pedal runs 9V-18V, so I am assuming this will as well. Can anyone confirm before I damage the circuit? Thanks!
 
My 100uf capacitor is 10V and the 10uf capacitor is 25V. So will this cause an issue?
Yes, the 10V definitely. Ideally electro caps should be rated at 2x or more of the supply voltage. a 10v cap is a bad idea on a 9v circuit. You can't exceed the cap voltage rating so 18v is definitely out.

Well shoot. If I run it on 9V with a 10V cap, what will happen? Can I keep it that way?

You risk blowing the cap. It can be replaced if it blows, but its a mess. it won't take much of a surge on a 9v supply to exceed the rating of that cap, and the rating has a tolerance as well, which further risks the situation. I would suggest replacing it with 25v minimum for 9v use and 35v minimum for 18v.
 
better to avoid problems later by putting in a cap now with a higher voltage rating. do it for your 10 uF cap as well.

does that mean don't power up your pedal if it is finished while you are waiting for new caps to come in if you had to order them? you could probably run it for short periods at 9v if you wanted to play with it, but I would not leave it plugged in and powered on.
