WORKING CONDITION: Very Good. This CS-50 sounds deep and lush. The keyboard feels even and responsive, and all of the functions work properly.  

PHYSICAL CONDITION: Very Good. There are some signs of use on the outer tolex covering, some light scratches here and there, but the chassis, iO jacks, buttons, and keys are all in very good condition. One of the cleaner examples you will find on the market right now.
