I tested these meaning i plugged them in, the lights come on. The FF, Rewind, on/off, eject and other buttons work. One commes with a pedal. I stepped on the pedal and it works meaning i hear the sounds. I cannot guarantee if this works meaning whatever it is meant to do, I would'nt know. Hope this makes sense. This is AS Is. I did not list as parts only because it technically comes on.
