Oh it's edited well no doubt. It's hard to explain to be honest.. It sounds like just for those small parts the bass is dialled in differently and has a different air to it like it's played at a different time. Hard to say. I can feel it is all I can say. Within the tune itself it's undetectable.
Punching in is common though. If you listen to the isolated bass of Flea on Under The Bridge, it's quite noticeable that he punches in for the outro unison passages with John towards the end.
Geddy's a total hero of mine and it doesn't matter to me that he may have punched in some fills at the time because after the creation of the album he burns it live. What I find interesting is that maybe he composed those fills after listening to the track, building each time, to add the perfect part.
God knows if that makes sense! Do bloody tired right now..
As you were.. 🤘
