Hey guys, I've had a block MXR Phase 90 for a while now that I originally got as a gift for a friend. It has an Led (Red), and a DC in, but the inlet is a smaller size then usual, the size of an aux cable (like earbuds) (side note: My Big Muff 3.14 also has this if that helps). Does anyone know why this would be? Functions fine with my 4X4. Would this be a Dunlop reissue perhaps? Thanks to all.
