Review on HexGaming Customized Controller Interchangeable Thumbsticks by Heidi Thompson

hold L1+R1+down+X for 5 seconds. The LED on the back of the controller flashes blue. Then press the button you want to map to the paddles. Follow the same sequence when you're done and keep holding until the lights go out. To reset the paddles, hold L1+R1+Up+Left+Triangle+Circle for 3 seconds until you see a red light flashing. Voila!
