Thank you for viewing. This product is an A&D GX-Z7000. Regarding operation, basic functions such as play, fast forward, rewind, and stop were confirmed using a cassette tape (UR). All switches and displays were normal. There is no scratchiness from the various knobs. However, regarding recording, only one channel records. Simple cleaning, head cleaning, demagnetization, and tape speed adjustment have been performed. The exterior shows signs of wear and tear due to age. Based on the above, this item is being sold as junk. Since this is a used item, returns are not accepted. Thank you for your understanding.
