I stumbled across this while researching alternate pickup switching schemes. This looks REALLY interesting!

That's a cool idea, I'd love to put that on a guitar. I doubt it would see much live use, though, I have enough trouble remembering to switch from the bridge pickup
edit: I watched all the videos, does it just activate and deactivate coils, or does it add capacitors and whatnot into the circuit too?
