This pickguard was designed in the 1970's when many players were removing the single coil pickups and routing the body to install a humbucker in both bridge and neck positions. As this is a custom design, the bridge pickup is spaced closer to the bridge at 3/8 inch than standard Fender pickguards which are spaced at 9/16 inch. This pickguard comes with two standard size covered humbuckers, and the mounting hole pattern will only fit genuine US production Fender® Stratocaster® from 1964 to current or post 2002 Mexico production. It will not fit Squier®, Fender® Japan, Korea, Indonesia or China production instrument. While many manufacturers may make a similar model instrument, this does not mean each pickguard of this type is interchangeable.
