Looks like someone tried shielding the cavity with aluminum.

Originally Ric used paper tape for "shielding" of the 4001 pick guards !

Aluminum would not be your best choice for shielding...copper tape is better and readily available.

There are a few theories as to the reason for the masking tape on the backs of Rick guards. I'm quite sure that shielding is not one of them...
