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).
Does that still hold if I use the Line-In instead of the Mic-In?
A guitar amp with line out, or certain guitar
FX processors will do, or you can try to find some cheaper device, look for at
least a impedance converter(transformer), or an active (battery powered) D/I box
with built in amplifier.
Any recommendations for a cheap device that just does the job nicely?
