Guitar hero Gibson controller inklusive Guitar Hero metallica for Xbox 360 complete with manual.

Original strap

The Guitar works generally fine but has a locking issue between the handle (part with the buttons) and the main Guitar. Basically it can shift off 5 millimeters and get disconnected. When playing it disconnects often and it needs to be held together.
Therefore not fully functional as it needs to be held together/fixed together. But if held together the Guitar works fine.

Let me know if you need more precisions or videos of the issue
