Gary is incorporating mu metal, magnets, controlled voltage, black magic and not a little sonorous incantation to reconfigure a fantastically complex wiring harness that includes (but is not necessarily limited to) a sustainer system and a MIDI system as well as the usual electromagnetic pickups; all artfully crammed into the electronics cavity of this otherwise distracted custom-made solid body electric guitar. Naturally some divination is called for, and Gary has spread his hermeneutic material in the most appropriate place: on top of the guitar.
Note to self: Research instrument anesthetics. Do guitars feel? Would it be appropriate to limit a guitar’s purported sentiency during a repair or modification?
