WAV: The Fender G-DEC 3 supports mono and stereo .wav files that have a bit depth of 16-bits and a sample rate of 44.1 kHz.
MP3: Mono and stereo mp3 files of all bit rates up to 320 Kbps are supported. Variable Bit Rate encoding is also fully supported.
Note: When using an mp3 file with the Fender G-DEC 3, looping will not work correctly due to the header information that is present in all mp3 files. This causes a small gap at the beginning of the file resulting in imperfect looping.
