if you don’t mind working for your sounds, the polychorus is about as good as it gets. you can come within inches of both the small clone and the DEM while nailing everything inbetween, plus it can self oscillate. i would argue that it has a far broader range of sounds than the dedicated units, although it is not nearly as easy to deal with. matter of fact, ive had mine two years now and i still can’t tell what sound im going to get just by looking at the knobs. the rate knob affects the effect’s depth just as much as the width knob, and proper settings on the feedback and tune knobs are absolutely crucial in attaining a decent sound.

that having been said, i don’t think my small clone has left it’s box since i got this thing and the only other flanger ive bothered with is the flanger hoax. the polychorus covers everything.
