When stolen from the Lonesome Drifter, dropping it and picking it up again will result in Karma loss. After dropping it again, it will be owned by the Courier. Sometimes this doesn't work, if this happens you can sell to a non-player character then buy it back to achieve the same result.
Writing can be seen scrawled on the bottom of the front side of the guitar. A lot of it is hard to read, but one of the writings says "Anne" with a heart next to it.
