I just test the tascam the only thing I see wrong with it is that the red record button on track 7 don't blink but if you click it it does work it's still arms the track and the CD rom sticks that's why keep a CD in it so you can open and close it but it sticks other than that I don't see anything else wrong with it I plugged it in I record on a couple of tracks sounds pretty good other than those problems some light scuff marks over time but other then that it works pretty good pretty solid.
