I was wondering if there's any special stuff i should concider besides the piezoelectric effect if I wanted to swap out electrolytic capacitors for ceramic ones....

well, I don't really no what difference it makes, but electrolyctic capacitors have polarity while ceramic don't. I'm not really concerned with the chemistry of this stuff when i'm building, but maybe someday it'll bite me. stay tuned as i might go get my 'for dummies' book.

When it comes to behaving like an ideal capacitor, an electrolytic is pretty much the worst. The only reason they're so popular is because they're really cheap, and they can get very high capacitances per unit area when compared to other capacitor types.
Basically all i'm saying is that going from electrolytic to ceramic should be fine as long as you make sure the values are the same and the voltage breakdown of the ceramic is sufficient. You only really run into problems when going the other way around, replacing a ceramic cap with an electrolytic one can cause problems.

What I have shown you is reality. What you remember, that is the illusion.

If the electrolytic caps are of a very, very small capacitance (Like...low uF to high nF) then you can go ahead and replace them. If they're blue, you might not want to replace them, since as far as I can remember, blue are decoupling caps.
