Stereo
Hi,
Absolutely Edge pans his delayed signals in stereo on the albums (when playing live, they run everything in mono obviously).
The stereo'd delay gives the guitars their big 3-D effect. Some songs are mono, like Bad. Pride is stereo (that's one reason it sounds so big), as are Still Havent Found, Walk On, and many others, although most are subtle. Listen to Indian Summer Sky, you can easily hear there's 2 delays, one panned left, one panned right.
