I didn't mean to tune the wires to accurate guitar string pitch. But
yes, strings have to be replaced from time to time ;-)

How should that work? If you ground all the strings and sense the
resistance between fret end and ground, you can't tell if one or more
strings are in touch with a fret. Even if you scan the strings, i.e.
ground only one string at a time it still seems difficult.
