Yamaha has intentionally blurred the lines between acoustic and digital in these AvantGrand instruments. They have a superb natural feel of a real piano action yet has a USB audio recorder and built-in bluetooth for wireless connection to a Smart device. This particular instrument was gently used in a non-pet and non-smoking home for a little less than 3 years and remains in excellent condition. Comes with matching bench, 2-year warranty and 1-year, 100% trade-up. Significant savings off new.
