I've seen 8 and 12 string basses before, and I know that they're really just 4'ers that have each string doubled, or tripled. But how would these extra strings be tuned, would they just be an octave higher than the string they're next to? Would you be able to play one of these monsters fingerstyle, or would they be easier to play with a pick? Lastly, what bassists/players or bands use, or have used 8 or 12'ers? Thanks.
