What Ibanez ATK is that?

I keep an eye on the Japanese made ATKs that come up on eBay and this one came up:

I have never seen an ATK with 2 knobs. My MIJ 300 has 4 knobs and the switch, like all ATKs I have seen.
Anybody knows what model that is?

So I think it is an ATK 100. The layout of the controls is a bit different from the pictures I found, but it could be because in the later models (MIK etc.) the 3 way switch has been migrated to an area less prone to accidental flicking.
It would be a passive bass then.
