okay to clear up issues, I have a 4-string bass tuned up half a step, and my 8-string guitar is tuned down half a step.
For parts that are on the lower 8th string, I play in the same octave as my bass guitar, but the sound settings that sound good in that style of playing sound odd when I play "normal" chords on the upper strings.
that's my problem, since I'm trying to get a consistant sound on the whole track.
