"who on earth would go through such lengths to fake a DM2??? siao ah?"
Not necessarily. For $285 USD - about $440 SGD, it might be worth it. DM-2s are *highly sought* and getting harder to find. Wouldn't even be that hard to fake - get a casing from any cheapo 3 knob Boss pedal, some closely matched spray paint, perhaps some cheap ass delay circuitry rehoused from a FAB or Danelectro or something and sell it to someone overseas...
What I find suspicious is that there is no mention of the differing knobs in his advert text. *Obviously* they are wrong.
FWIW, I think it's probably real, but bought from someone else who replaced the knobs by someone who didn't know they were wrong.
Incidentally, a quick search of Google reveals that many other DM-2s have the smaller 'Delay' word so that is not necessarily a giveaway. On my DM-2 the vertical of the 'D' is in line with the 'O' in the word output and the left side of the 'y' is in line with the left of the word input.
