The full size [ZN1] did have the control box, which allowed digital control over the bass/treble. But unfortunately mine died after a few months of ownership.
I think mine is still working (I have no idea, I haven't really used it since I bought it even though I thought that I intended to probably write a brief review at some point because that EQ box is a nice idea, however executed not so nicely (placement, weight, popping noise when turning on/off, some mild hissing)), but the battery life is rather poor (but that's what it already was right from the beginning).
