This seems like it might work. I know there are a lot of tube lovers out there, and if you have some thoughts as to how this might work, and how it might compare to a tube bass head, say the Ampeg B4H (the new one), that would be helpful. Is the valveking too good to be true for a bass player? I play passive fender basses, and like r&b, blues, reggae, jammy kind of stuff. I love the warmth of tubes, but I'm a poor boy Thanks!
