I am still relatively new to pedal building so I apologize if this is an nonsensical question.

The SWAH build calls for two 1uf MLCC, can these be replaced with film caps?

The only 1uf MLCC’s I can source are X7R/X5R types and I have read a few places these aren’t great for audio as they create a sort of piezoelectric sound that gives it a noise/distortion. I guess C0G solves this issue however I couldn’t find 1uf MLCC C0G to save my life.
