One-of-a-kind circuit bent walkman-style tape player. Features on/off toggle, LED indicator, speed control knob, speed stutter button, two screeching feedback buttons, and a crackling stereo switching knob that doubles as another screeching feedback controller when the speed control is turned all the way down. Runs on 2xAA batteries. 
 
Note: Battery compartment located inside the deck opening (I overlooked the access to the battery compartment until long-after I had already bent it, thinking that the only way to change the batteries was to take it apart.)
