Read the Cyril Bateman PDFs about the best you can find on the web.

Good design is about selecting the cap for part in the circuit it is in. AND for guitar amps and other audio you might not want the best you may like one of the the class 2 ceramic disk types caps sound.

There was a circuit that used an old ceramic cap to create a LPF around 10k and it sounded SAWEEET. just saying.

But I agree eletros are to be avoided when possible.

There are ceramics and ceramics

A NPO/COG ceramic is probably the best capacitor you can buy. If the voltage/value/tolerance/size is good, use it.

An important place for this is between the capsule & FET/triode on a capacitor mike. Polystyrenes in that position are microphonic and silver micas introduce noise. See Bateman and also Scott Wurcer in his Linear Audio series.

I did post class 2 on purpose.

Another thing with microphones and guitar amps and guitars is maybe the microphonics is what adds to the sound, could be good or bad.
