However if the microphone effect in a ceramic capacitor is primarily a piezoelectric phenomenon then maybe your idea would work.
Ceramic capacitor sound quality.
In any case i doubt that the audio quality would be adequate.
Ceramic capacitors are in the main microphonic but polyester caps are not.
High current impulse loads or high ripple currents can generate audible acoustic sound coming from the capacitor but discharges the capacitor and stresses the.
A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric.
It seems to me that an ordinary capacitor under dc bias would behave quite differently.
However when most ceramic capacitors are biased the capacitive rating can decrease by as much as 50.
Polycarbonate capacitors are stable for use in audio oscillators.
The quality factor is defined as the reciprocal of the dissipation factor.
A silver mica and a ceramic are also included so that the line up contains an example of most of the possible choices one might consider for a crossover or riaa network.
In fact this isn t so.
Ceramic capacitors are generally not recommended for use as ac coupling in audio.
Thd measurement data pulse noise can be reduced when used in a digital amplifier s low pass filter.
Replacing passive components to improve sound quality.
The geometry of the capacitor doesn t matter at all to the sound so you can use any capacitor that is 1 3 9uf 2 rated 100v or more and 3 non polarized.
Ceramic capacitors have low resistive leakage and are stable over time.
Compared to ceramic x7r characteristics and tantalum capacitors the distortion level is low and high sound quality of set is achieved.
Standard capacitors are perfectly acceptable for audio and will rarely if ever compromise sound quality unless used beyond their ratings or a completely inappropriate type is selected for the application such as a high tempco high k multilayer ceramic in a filter circuit.
There are many factors but in a guitar application just about any modern capacitor works well.
Stamler from reading circuit design texts one would think that a capacitor is just a capacitor and that different types are interchangeable in practical use.
If you pick one that is also low esr it would better approximate a perfect l c circuit and so in theory that might sound better crisper or punchier as the capacitor.
