Do I need to turn my computer off before unplugging the Fender G-DEC 3's USB cable?
Unlike most other USB audio interfaces, the Fender G-DEC 3 is hot-swappable. This means that you may plug it in or unplug it from your computer while the computer is running. There is nothing to eject or un-mount from your computer, even when the Fender G-DEC 3 is being used as the main audio device. However, while USB drive mode is enabled on the Fender G-DEC 3 it is best to eject or unmount the disk image from your computer and exit USB drive mode before unplugging the unit.
