It is fully original, and based on the serial number, it is believed to have been manufactured in 1980. It is said to be the predecessor to the Ibanez AD-9 and later Maxon delay series. This effector operates on 18V and can be used with a DC18V center-negative adapter or two 9V batteries. Although not a genuine MAXON product, a Moridaira-made DC18V adapter will be included. Please refer to the attached photos. Operation has been confirmed, and it works without any problems. However, please understand that this is a very old product before purchasing. Thank you very much.
