Blend a clean DI with a separate dirty amp path.

Why it sounds like that

The Pot is one of the songs that feature Justin Chancellor's buoyant bass riffs. For the 10,000 Days recording, his bass was tracked as two separate signals, one clean and one dirty, so they could be blended later. The two amps were Gallien Krueger 2001RB heads into Mesa Boogie cabinets. His bass also ran through a Demeter DI box straight to the console, and there was really no EQ on the bass.
- Mix reports one of Chancellor's two amps was set to a clean tone and the other to a dirty tone on 10,000 Days, tracked separately so they could be blended later.
- Joe Barresi said there was really no EQ on the bass during the 10,000 Days recording.
