Why it sounds like that

Justin Chancellor wrote the riff of Forty Six & 2 before he joined Tool, and it was one of the first things he and Adam wrote together once he was in the band. While Ænima was recorded, he borrowed a friend's Wal bass, originally fretless, and its tone fit in with the band. His tone has had a longstanding relationship with Wal basses. He plays with a pick and hits it pretty hard.
