Thus, the placement of this component is important.
How to find coupling and decoupling capacitor values?
In the case of (AC) coupling capacitors you want the most optimum capacitor for your signal frequencies. In practice the actual value of the capacitor does not matter too much as long as it is "enough". For example, to suppress a supply ripple of 100 Hz, a 10 nF capacitor isn''t going to help much.

Stop Worrying About Coupling Capacitors!
Coupling capacitors in series between stages of an audio circuit generally have a large enough value to roll off starting below 20 Hz. Since little audio voltage is lost across a coupling capacitor at the higher audible frequencies, in theory their distortion should not be a factor. This is exactly what I set out to prove or disprove with my tests.

This safety margin is vital for reliability, especially in circuits …
Ultimate Guide To Capacitors In Guitar Pedals
As mentioned, capacitors will block DC while allowing AC to flow through them. The signal from a guitar is AC, while the current in the actual pedal is DC; if these mix there can be interference and noise in the pedal, which is obviously bad. To prevent DC from flowing back into AC sections of the circuit, a coupling capacitor can be used
