signal cap question?

does this apply to stompbox circuits also or is it just something to be mindful of in tube amps?

thanks guys.


peace,

 Well i'll be damned! If that's really true, I can't imagine how it would NOT apply! Now I gotta wonder about a few builds that worked, but just didn't "sound right"...

In the case of some types of capacitors, such as ceramic disks, multi-layer ceramics, or silver micas, there is no "outside foil", because the capacitor is made of a single-layer, or stacked layers of dielectric material and conductor.  The orientation of these capacitors makes no difference.  Also, some higher-voltage film caps (typically the 1000VDC/450VAC and higher values, such as the Orange Drop 716P high-voltage units) use a "series-wound" technique that has two separate sections, side by side, with a common "floating" connection layer, usually at the bottom of the layer stack.  These caps will have no inherent shielding either.

Could that be the reason that some folks advocate ceramic caps? Dammit, I don't have a scope, so I guess I'm screwed. (provided this is factual, and applies to low voltage applications)
