Test a Guitar Hero controller
A guitar controller is a gamepad with a strange shape. The raw list is the right view.
What to check first
Connect the dongle or the USB lead, open the generic tester, and press one fret at a time. Note the index. Strum often moves an axis or two digital buttons. Tilt, if the model has it, may be another axis. If nothing appears, the OS does not see the receiver. This page cannot repair a missing dongle.
- One fret at a time, or you will mix indexes.
- Whammy is usually an axis, not a button.
- 360 guitars often need the matching receiver.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
