These are replacement pickguards for USA and Mexican Fender Telecaster deluxes.
These pickguards have 15 mounting screw holes (including the center hole), are equipped to take 4 CTS sized pots and a right angled 3 way toggle pickup selector switch. The pickup holes are sized for Wide Range humbuckers. These are a very different size to normal Gibson sized humbuckers and the two are not interchangeable.
