Re: What can get this tone ?
According to Butch Vig on the Nevermind behind the scenes, Kurt tracked using a Mesa (they didn't say what kind but probably a Mark something like a IIC+ or a III) '59 Bassman cranked and sometimes hit with a DS-1. In some songs like Drain You, they would track up to 10 guitars at once but not on every song.
To my ear, that sounds like one of the boosted bassman tracks.
