I bought this power adapter for my Digitech Jamman Delay pedal and was very disappointed that 1) it's not a Digitech product but a "GreenEdge" product and, worst of all, 2) the connector for the pedal is too big and doesn't fit. So it's useless to me, unfortunately. Note also that I brought my pedal to Europe from the USA. There may be a difference in the size of this connection? The difference in size is very small--difficult to see with the eye. But it does not fit and does not work with the pedal, so I have to give it 1 star. No idea if Digitech still manufactures these...
