SOLVED Pythagoras, quick newbie question on capacitors

[Url2]

Hi,
I’m finishing my first FV1 build, and I just noticed that I miss 1 electrolytic capacitor (1u) for C9.
Can I use a MLCC capacitors of the same value instead?

Do you have a 1uf Tantulum, that would work!

I only have a couple of MLCC left for that value.
Do I necessarily need a polarized cap in that position cause one leg is going to ground? Sorry for the basic question, I’m still learning the basics

I'm waiting on confirmation if MLCC to ground would work also.

I’ll finish it up tomorrow (it’s 2 AM in Europe), but I’m still waiting for the EEPROM to arrive next week.
In the mean time, can I somehow test if the MLLC will work and spare me a parts order for 1 single missing capacitor ? If not, I’ll just but some more caps

C9 doesn't necessarily have to be polarized... MLCC will be fine.

Thanks a lot!

now that the ”issue” has been sorted out, what’s the general purpose of polarized caps in pedal circuits? I noticed that in this build electrolytic are used only when connected to the ground. Is it just a design/shape/price choice or usually this configuration has a function?
