Edit: And I wrote that before I scrolled down and saw the AC30s on oriental rug photo. Another Edit: Or the video on MusicRadar, talking about how Korg developed the pedal with help from U2s guitar tech.
I like how they gave a nod to the original unit with the knobs and buttons.
The ability to set a tap-related interval for left and right delays independently looks like what I've been waiting for, at least if the feedback is shared in some way. I want U2 flavored ping pong, not totally independent delays. If I could just get a non-corrupted version of the manual I could find out.
