Why it sounds like that

Krist Novoselic played a blonde Ripper bass on Nevermind, through an Ampeg SVT amp. His bass was recorded with a DI and microphones combined, which made it extremely warm and fuzzy. Of the two microphones placed, only the FET 47 was kept, and it has a thumpy, mid-range sound. The bass sits chilled-out and backseat behind the main riff. This is the Nevermind album rig.
- Keep the bass chilled-out and back, letting it sit behind the main riff.
- Bend with the left thumb and add vibrato on the notes.
