Static discharges are almost 'delta pulses' and hence have a very high frequency content. For very high frequencies, a capacitor is actually a short, not an open! > btw "frequency dependant" .... no, you would choose a capacitor whose > capacity > is small enough to not interfere in this respect. Uhmm.. you mean large enough.. The larger the capacitor, the lower the cut-off frequency. You are making a high-pass filter with the C and the impedance of the amplifier.
