Thank you for viewing. This is the DONNER GA-MINI II. It's compact and simple, making it perfect for personal practice. I think it's also very easy to use as a first amp for beginners. Adapter and batteries are not included. This is a listing for the main unit only. It's in very good condition, but it is a used item, so please consider this before purchasing. Features an AUX IN jack. - Model Name: GA-MINI II - Input Terminals: INPUT, AUX IN - Volume Control: VOLUME, TONE - Drive Switch: OFF ON DRIVE
