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.

You cannot do
that in a sane way - the output of a guitar pickup needs to be
modified (amplified and converted to high impedance) before, otherwise the
signal will suffer (treble loss).
I believe you, but I'd be grateful if someone could explain to me how
one would know that the treble will suffer? I mean, we were talking
about real impedancies, and to determine how the line will react with
respect to certain frequencies we would need the complex part...
