Can you use aluminum tape to shield guitar?
You can do this a few ways: copper or aluminum tape, or graphite shielding paint. Shielding paint looks better, but it is expensive. It isn't a good investment unless you have more than a handful of guitars to shield, and it isn't something you can just pick up at the local hardware store either.
Does guitar shielding work?
Guitar shielding works very well to reduce 60Hz hum (or 50Hz for some countries) and is effective at blocking the unwanted signal since a Faraday cage cancels an electromagnetic field for anything inside the cage.
