The Roland Aerophone mini AE-01 is a compact digital saxophone with USB connectivity. - Model Name: Aerophone mini AE-01 - Brand: Roland - Included: USB cable, instruction manual, warranty card - Color: Blue - Accessories: Mouthpiece I purchased this online about two years ago. I used it 2-3 times out of curiosity, but it wasn't what I expected, so I haven't used it since. I will ship it in the original box it came in. It uses dry cell batteries for power, and I have not used a charger. I will also include a new, unopened replacement mouthpiece. To ensure careful shipping, I will ship it on the upcoming weekend or national holiday. Thank you for looking.
