The impedance of a guitar PU is mostly inductive, i.e. it rises with frequency. So if you load this with a low impedance the effect is that of a low-pass filter. That's the simplest case - in practice the inductance can resonate within the audio band when connected to a cable (which is capacitive) and this is why guitar cables can have a distinctive sound. Anyway, for a guitar you need a high-impedance input, not a microphone input.
