The DG-1 was the first in the line of Casio Digital Guitars; a revolution in design, sound and playability whilst severely lacking in practicality. These early ones have a little less functionality with a little more retro styling, and lacking MIDI functionality, however it still features loads of built in sounds and rhythms for those looking for a slightly more stripped down and simple version of the DG-1 successors. With original gig bag. Tested and works fine.
