This will always be a source of amusement to me because I had to name one bassist who smothers his signal in so many effects as to shade the bass he's using, it's Justin Chancellor. To whit, I had always found it interesting that fans were so eager to buy a Wal bass themselves. I had heard, over the years, suggestions that a G & L L2000 or Musicman Bongo would be a passable alternative and I'm inclined to agree.
Which is not to say that Wal don't have a signature tone, they do. They almost stand out like a sore thumb through that unique 'quack' noise they make. I just find that quality almost entirely missing in the rather anonymous tones on Tool records.
As for the new Tool song, I think it's okay. It really doesn't sound like 13 years worth though, and that is following on from '10,000 Days' that was a weak followup to 'Lateralus', which was in turn pretty disappointing. I don't dislike the new song, but it sounds entirely like Tool by numbers, the sort of thing they could write and play in their sleep.
