Thank you for viewing! ●Product Name/Model Number YAMAHA MT50 Yamaha Multitrack Recorder MTR Cassette Recorder I have confirmed its operation, and recording, playback, rewind, and fast forward all work without problems. The faders also move smoothly, but there is some crackling when listening through headphones. I have not checked the AUX return. I've used it quite a bit, but I think it's still usable. The soft case is dirty. Please purchase if you understand that this is a used item. ●Included Items Main unit, AC adapter, case
