This is a Pioneer cassette deck CT-6. I don't have the equipment to fully test the sound, but I have performed some basic checks. The basic functions like play, fast forward, and rewind seem to work without issue. Other functions are untested, so I am selling this as junk. Please purchase if you are able to maintain or repair it. Shipping will be in a simple package using recycled cardboard. Due to the size of the item, returns and refunds will not be accepted after arrival. Please understand this beforehand. Thank you.
