Custom controllers are controllers that can be heavily modified to enhance the gaming experience. These controllers are compatible with certain modern gaming consoles. As of 2015, gamers can buy custom controllers made for the Xbox 360, the Xbox One, the PlayStation 3 and the PlayStation 4.
Some possible modifications include custom buttons, custom analog sticks, a custom paint job and paddles that can be placed on the back of the controller. These paddles imitate whichever buttons on the front the gamer chooses. This allows for the gamer to access and use these buttons of choice without taking his fingers off of the analog sticks.
