First off, I'm really unsure if I'm posting in the right category. I'm in a death metal band; really old school, riff-based music. It's not at all the music I listen to, but it's very fun to play. We have a song with a part that's more chaotic, if not black-metalesque, with our one guitar doing high-pitched minor chords in eights over fast drums, that later becomes a blast beat, and I've been thinking for a while of what I should put there. I liked the idea of putting up a bass solo, with fast, chromatic/dissonant stuff, and maybe some effects. I have little to no composing experience, and some theory. I'd appreciate if someone could give me some tips, whether regarding approach, play styles, effects. I play a 4-string tuned in C#.
