A 61-key arranger keyboard equipped with a high-quality piano sound source. I bought it about a year ago, but I've barely used it, it just got dusty. The power turns on without any problems. I am selling it because my new residence prohibits musical instruments. - Model: Roland E-X10 - Accessories: Instruction manual - Speakers: Built-in speakers - Number of keys: 61 keys - Power: AC adapter Thank you for looking.
