What is a modded PS3 controller?

Modded PS3 controllers are video-game input devices for the PS3 that have been altered by users. Modifications may include different exteriors that change the look of the controller as well as internal adjustments that enhance game play and deliver additional benefits and features not included in the stock controller.

Users modify controllers for a variety of purposes. Cosmetic modifications alter the color of the controller, whereas functional modifications change button layouts or the way each button or stick transmits information to the video-game system. Many online stores sell modded PS3 controllers designed to match the appearance of, or simplify, user input for a variety of popular games.
