The 15-watt G-DEC (Guitar - Digital Entertainment Center) allows you to practice along with onboard MIDI drum loops and bass lines in many styles and speeds, create your own guitar loops with the Internal Phrase Sampler, stream MIDI files from your PC and use the auxiliary input and filters to zero in on different instruments in any song from your mp3 or CD player. It's a blast! Like your very own band-in-a-box!
