Why it sounds like that

Krist Novoselic played a blonde Ripper on Nevermind, and his amp was an Ampeg SVT. He used a DI on that album, though not on In Utero. The bass sound came from a combination of DI and miking, which made it extremely warm and fuzzy. The microphone that was kept has a thumpy, mid-range sound. This is the Nevermind album rig, not a setup confirmed for this song.
