Station Wah - C2 22p sub?

[mitch]

The Station Wah build docs call for a 22p ceramic capacitor in C2... I don't have any 22p, but I do have 20p MLCCs. I measured them with my multimeter hoping to find one close to 22, but most are actually in the 27-30p range.

I've completed 25ish successful builds but they've all kind of been pretty paint-by-numbers so I don't really know why/how things work in the circuit and I have a few questions.

• Is this substitution ok?
  • Would I be better off trying some series/parallel caps to get closer to 22?
• Any significant changes to the sound?
• Any other components I should change?

I'm also using a 570 mH ME-6 inductor, if that matters.

Thanks!

A 20p will be fine.

@jimilee thanks - that's what I assumed but wanted to verify first!

I used a 30p in mine. Its purpose in this circuit is just RF rejection at the buffer input, so so long as it's kept to a lower value, it shouldn't have an effect on the sound.
I also used the ME-6
