Re the bass, I thought about a li'l time-shifting, but then thought, if I was in this band I'd want my tone (bassist, here).
My approach, my mixing philosophy (as it were), is to assume that the tracks I am presented, especially when recorded by the band, captures their basic sound as they want it.
I look to maximize the presentation, without altering that sound too much, e.g.
, I'll use compression and EQ on vocals because singers wanna be understood, I'l use delay, etc. to make it interesting. But I won't use pitch-shifting unless there's a clear clam, and never as an effect unless requested.
So on that bass, I did a little pass filtering and compression/limiting, and I used the DI about 3dB under the mic'd track for the oomph
, and I did add a cuppla dB at 900hz (1.3Q) for clarity.
Then I rode the levels to keep it audible, which of course brought the kick up to keep it audible ...
But lemme say I agree with everyone else here - helluva voice on that guy! I like this band.
