Presets do not contain the actual Band Track file, only a pointer to the Band Track file location. To move Band Track files to and from the Fender® G-DEC® 3's internal memory, you can use the Fender® FUSE™ software (http://fuse.fender.com) or the USB drive menu in Utility mode.
To enter Utility mode, simply hold the EXIT button on the Fender G-DEC 3 for about 3 seconds. Then navigate to "USB Drive" and press either of the two soft keys in the center under the amp's display to enter USB Drive mode. Press the amp's Exit button to exit.
