Voice Recorder Vintage '90s Electronic Musical Instrument Toy Instrument Toy Instrument - Model Name: HAUNTED Yak Bak SFX - Color: Orange - Function: With sound playback button I tried putting in batteries, but it didn't work. It used to work. It's a toy that can play sound effects and recorded sounds. The screws on the battery case are also quite stripped. For those who can fix it, or for circuit bending, etc. Thank you for looking.
