Again, why are you looking for something when you are already satisfied with your clean tone? That's like cheating on a gf...you're satisfied but you WANT more. Not NEED. Now I know why you were disappointed with the m9. You probably plugged it in and thinking it was going to make you a better player, make your rig sound like $5000, make you a rock star. You say you're a metal head but when have you heard effects on bass other than some type of overdrive/distortion on metal songs (not absolute but most of the time)? I'm sorry if I'm coming out like an A-hole but the more I read your posts the more I think you have no clue what you're talking about. I can't even begin to imagine how you are trying to use your m9.
