I’m listening to your mix on the grotboxes in my office right now, and I have some comments:
The intro guitar is panned to hard left. I find it irritating if some instruments are only coming from a single speaker. Together with the second guiter the wide panning sounds okay, though.
The vocals seem to be louder than anything else. (This may be the fault of the grotboxes.)
There’s some effect on the whispered and screamed parts of the vocals that emphasizes those parts weirdly.
Most mixes done in Reaper or Bitwig on a MacBook Pro using Sony MDR-7506 headphones and some hifi system with old Saba speakers in a small-ish untreated room. If I commented on your mix, please check the board for my mix and reciprocate. :) Thank you!
