This project is an unofficial web-based replacement for the discontinued Fender FUSE application. It allows you to control your Fender Mustang amplifier directly from your browser via USB.
- Restore Lost Functionality: Since Fender discontinued FUSE, this tool provides a way to manage your presets and settings again.
- Web-Based: No installation required. Runs entirely in browsers with WebHID support (Chrome, Edge, Opera).
- Deep Editing: Access "hidden" amp models and effect parameters that are not accessible via the physical knobs.
- Signal Chain Management: Visually configure your effects loop and signal path.
- Connect your Fender Mustang amp to your computer via USB.
- Open this application in a supported browser.
- Click "Connect" to start editing.
This application communicates with the amplifier using the USB HID protocol.
For a deep dive into the protocol implementation, including packet structures, command codes, and model identifiers, please see the Protocol Documentation.
