G'day! Just picked one of these things up for $25. Sounds quite good - a good "organic" little box. Can't find a manual (although it only has three knobs and I can use it, I like the manuals to make it "complete").
The more I poke around with this thing the more I like it. Technically it's not close to a DM-2, but it's actually OK. Presumably sonically it's not a DM-2 either (I can't tell - I've never heard a DM-2 in person!).
I had thought of getting a Belcat cheap and cheerful delay (another thread in this forum) but this Ibanez popped up instead and I'm really happy with it.
