I have confirmed the basic operations of play, record, rewind, and fast forward. I tried recording with dbx, and it seemed to have an effect, but I have a bad ear, so please don't rely on that too much. I have cleaned the heads and pinch roller, and demagnetized them. 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 this as a junk item. No returns or claims accepted. - 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.
