I mean it when I say cheap 80's digital reverbs too. From everything I can gather, the Korg DRV-1000 was a budget unit back in its day. And they don't go for much today either (mine was only $100 at a Music Go Round)

It's pretty basic, with a set of "programs" (i.e. "small room" or "gated" or whatnot) and then simple mix & time controls. The time control is extra weird since it's stepped, not a continuous smooth pot. So you dial in the time via 8 or so preset timelengths.
