so far, i've found that setting one to half or double the speed of the other gets a pretty cool rhythmic drum-line effect to it, and you can get swells if you put the second one at half speed and play full chords with a little dirt. i also have found that ping ponging them between two amps is really fun. anything i'm missing?
You can do quarters into dotted 8ths...that's a fairly common one. Or the other way around. Or dotted 8ths into reverse quarters. Anything into multitap. The combos are endless with a couple multiple setting delays.
