There’s smth weird with guitars when I’m listening on speakers (on headphones it’s ok) – when I’m listening to only one speaker everything is fine but when I’m between two speakers it feels like the two channels are clashing witch each other
You have a serious phase issue in your mix. All the guitars is out of phase with each other. When I play your mix in mono, all the guitars are gone. Sorry! If you are allowed to repost your mix, I would fix it if I were you. Good luck.
