We have been unable to find a listing of this accessory in a catalog, so we don’t know what the retail price would have been in period. The cable is approximately ~10’ (feet) long with standard 1/4” (inch) jacks for an electric guitar or bass. This used example was sourced out of Japan (pictured at the bottom of the page). The cable has red insulating rubber and the ends have a small phillips screw presumably to allow the user to make repairs to the solder connections as needed. The ends have the Daion logo in white on red plastic.

Our example is red (bottom of page), but we have seen one other example in green (below).
