I have confirmed the basic operations of play, record, rewind, and fast forward. I also tried recording with dbx, and it seemed to have an effect, but since I have a bad ear, please don't rely on it too much. I have cleaned and demagnetized the head and pinch roller. I have checked the azimuth and tape speed using free software, but please understand that it is not an expensive measuring instrument. There are scratches and some stains that cannot be removed, so please consider it as a junk item. No returns or claims, please. - Model Name: V-450X - Type: Stereo Cassette Deck - Recording Level Adjustment: Soft Touch Operation - Tape Selector: Metal/Normal - Input/Output Terminals: Line Output/Input Terminals - Counter: Tape Counter Thank you for viewing.
