"You know, [whether to play with pick or with fingers] is a choice that bass players in this kind of music have to make. Sometimes it makes sense to try and go as fast as you can, even if it is a little jumbled, maybe in a tremolo picking part. If both guitar players aren’t quite lining up anyway, then I think it’s okay to have things sound a little jumbled. It gives it a frantic sound, and that might be exactly what you’re going for."
