Bad poll options imo. You don't even hear those instruments anywhere else than in ghey folk metal. However, I think that the bass guitar is the most unappreciated instrument in rock music general. Ignorant people tend to think that the bass is just for some extra feeling, but in reality the bass is basically the foundation of a song. Especially in heavy metal the bass is sometimes pretty underrated, although the genre has hundreds of very talented bassists. Maybe progressive rock/metal is the only genre that truely appreciates the bass to the max. However this is not the case all the time, but the main point in my post is that bass guitar work should be more appreciated.
