Instructions
Inspect the controller and consult to determine what type of plug you are converting from. A standard PlayStation plug has not changed over time. If you are using a wireless guitar, the conversation steps may not work as they would with a wired guitar. Next, look at the system you are trying to plug into. The Xbox and Xbox 360 have different controllers.
Buy a conversion device. Once you have determined what type of conversion is needed, you will need to purchase an adapter. For the Xbox 360, the most popular adapter for PlayStation controllers is the XFPS 360. If you are looking for a cheaper option or are trying to plug into the first-generation Xbox, you can find many other adapters.
Plug your PlayStation 2 guitar into the adapter and plug the adapter into your Xbox. Some of the functionality of the guitar may have changed, so play around with it until you are familiar with the controls. If your controller requires power, such as with a wireless guitar, it may not work. If the controls did not convert properly, you may have to return your adapter and try a different brand.
