Great japanese delay pedal. As far as I know, this one and the series it was included in was produced by Maxon and then branded as Ibanez. Like most of early digital devices it has a bit darker tone but without any loss of clarity; versatile controls with a wide range of possible settings; no modulation but a certain analog manner to it, — repeats aren't cold or metallic at all — apart from that it lacks any noise and is as silent as it gets. Overall, great piece of bold vintage equipment.
