Yeah, mega clipping happening.Guitars sound like di's that are overdriven in your DAW. Sounds like your concerned about overall volume because your mix is pretty loud. If you are doing a shit ton of master bus processing for a mix then you are doing it wrong. Leave this naked with the exception of some light buss compression to mix through. Once it sounds good on its own, then you can worry about volume. Too many people try and mix and master at the same time which isn't good. You can potentially leave a limiter on the master buss bypassed while you mix, occasionally engaging it to see how it affects your mix decisions.
