The Seymour Duncan La Brea pickups are voiced to provide a heaped spoonful of bright, clucky twang, but also feature a tight low end to round out the full frequency spectrum. The bridge pickup uses alnico IV rod magnets and vintage era-correct cloth push-back wire, and boasts a hot output of 7.44k, while the neck pickup features alnico II rod magnets with an output of 7.55k. 
Listen to how they sound in the video, featuring Paisley himself, below. This dude is a serious player, and even if you feel that country is the scourge of all genres, you’ve got to respect his chops.
