nothing too crazy here, one track of clean amplitube3 and one of BOD iirc
EQs and comp at that point I think, maybe some dist/saturation on the BOD clip too, I dunno anymore exactly.
For bass tone it's a lot about the instrument and how you play it.
If you go with ermins approch you'll get a different result though.
His way of mixing the bass for metal is all about controlling the low end, so it is totally limited in it's dynamic range. Works really good in mixes, but doesn't sound like that on it's own.
Less "breath" to it.
Both can work, depending on how you want it.
