Product Description: I have confirmed that it works with an AC adapter I have at home. I have lost the original adapter, so this listing is for the "main unit only." It has built-in effects, making it ideal for beginners and for practicing outdoors. Please be aware that this is a used item. Instant purchase OK. If there are price negotiations in progress, instant purchase will take priority. Please note that if a price negotiation (dedicated listing) has been agreed upon, your instant purchase may be canceled.
