Pharaoh fuzz caps question

[dannoceti]

I'm building the Big Muff Pharo from this schematic which shows .047uf coupling caps. I realized after I built it that to be more like the blackout effectors pharoah I need to change them to .47uf caps.  I ordered some from mouser (Epcos box film) but the shipping was delayed.  I wanted to ask the group what they thought about using .47uf multilayer ceramics (NTE) from my local electronics store? Should I wait for the mouser order or just pop these in?

I'm not sure they would work, but they are noisy I've been told.

Thanks Jimlee, think I'll wait then

AFAIK the coupling caps in that schematic C5 C13 C3 should be 0.47uF and not as noted in schematic 0.047uF.
So the multilayer ceramics would be the correct value in those positions. Not sure if they are more noisy, but I prefer to use plastic film caps there.

Yeah, they're supposed to be 470n, not 47n. I opened up a friend's Pharaoh to check.

For coupling caps I would use film caps instead of ceramic.
