This is so, so cool. First up, it's a gorgeous analog chorus. The tone is gooey, warm, wobbly and glorious, a worthy contender to the CE-2 and instantly lovable. Second, in stereo mode, you get a separate dry/effected blend control for each output: oh boy. You can dial in a subtle wobble on the left and a wild, seasick-room-spinning on the right... glorious.
