can load MP3 or WAV files from your computer onto the SD card 
"Audio" folder to use as Band tracks. Presets, phrase and MIDI 
tracks go in their respective folders.

cards. Log on to fender.com for a list of approved brands.

speaker will be muted.

Fender® Fuse™ software (included) to transfer/edit presets and media 
files beyond what the G-DEC 3 is capable of alone. See the Fender 
Fuse software owner's manual on the G-DEC 3 DVD for details. 
 The USB connection can also be used to stream stereo 16 bit, 
44.1k audio (playback and recording). The included G-DEC 3 DVD 
contains Ableton® Live Lite 8 Fender Edition recording software
