Used AE-30 in great condition. I got this instrument used and since purchasing it have only played it a handful of times. The finish on a few of the keys is blemished, but it doesn’t affect the playability or feel at all. The battery terminals are very clean and free of any signs of corrosion. Please see the embedded YouTube video at the bottom of the listing for a quick overview of the instrument along with clips of it playing. Please feel free to message me with any questions you might have that I didn’t address in the description or video!
