The channel I mentioned measured the internal cabling of an 60s Les Paul and it had a WILD capacitance swing changing with humidity (more than 100% of the orignal value). Meaning the capacitance-induceed resonant frequency of the guitar would shift strongly over the course of a gig. Needless to say, this is probably not a thing anybody is looking for.
