actually, nevermind. i just realized the dissonance i'm looking for is actually relative and relies on the b string being roughly an eighth tone flat. leaving the low e string at roughly a quarter tone flat allows the entire song to be played on one guitar. so, that's the tuning, if anybody is keeping track.

(note that the terminology refers to a whole tone. so, when i say an eighth tone flat i mean 1/4 of the way from b to b flat and when i say a quarter tone flat i mean 1/2 the way from e to eb.)
