You bring the talent. We’ll supply the kick ass wiring…  


Hoagland Custom, located in sunny Fernandina Beach, Florida, has specialized in custom guitar wiring and pickup building for over 25 years… & we love what we do!

The original two-pickup Esquire wiring is characterized by the absence of a real tone control. Instead, the second pot acted as a blend or pan control between the two pickups, and this was only engaged with the 3-way pickup selector switch in the rear position. In May 1952, Leo modified the circuit to incorporate a true tone control by skipping the blend functionality and discarding any two-pickup combination.

Today, we know that it was not Leo’s idea alone, and this change was mostly made because of Bill Carson’s suggestions. Carson worked as a professional Western swing guitarist and was Leo’s favorite guinea pig for testing his Telecaster and early tweed amp designs. Carson never really liked the blender wiring on his Telecaster and came up with the idea to incorporate a real tone control.

This circuit is often referred to as the “dark circuit” or “Blackguard” wiring and was roughly used from mid-1952 up to late 1967. Within this 15-year period, the circuit stayed mostly untouched, but Fender changed the specs of the two capacitors several times over the years.

While all of our wiring solutions are built to be installed rather easily, we always recommend that you have a guitar professional at your local guitar shop install it for you.
