The instrument looks like an oud that was left in the wash machine and shrunk. In terms of tone... well, a good cobza functions like a drum machine - either knocking out driving east Balkan dance beats or picking out the intricate background rythyms (tiituri) patterns of Romanian lautar music. The problem is, there really aren't many good cobza players left. The cobza is an instrument that is dying out fast. Recorded examples of Moldavian Csango players of cobza were made during the 1950s and early 70s, by which time you could hear that the players had already lost their skill.
