Carparelli Full Aluminum Pickguard Shield. Made from (0.30MM) thick 6061-T6 aluminium just like what was used on the early 60's Strats. It is designed to work with almost anybody's traditional strat® guard, with slightly larger holes for clearance. This shield is far superior to foil by allowing you to tighten pots and switches firmly without fear of breaking through a thin foil. You will no longer need ground straps from pot to pot thus eliminating a potential ground loop and unwanted noise.
