Steve, I just listened to it.
First things first, I liked what I heard.
If you hadn't said that you don't like the quitars' sound e.t.c, I would mind anything in it. To be more precise, everything in the song (vocals, drum parts, guitars) could be intensively produced this way...to intensively sound this way.
But from your previous posts I understand that this is not the case and you expected the guitars to sound more alive, more "in your face" and this is not what you hear from the KPA in the first place (weird, because what I hear is what it gets recorded, unless i misunderstood your comments)
Well, if that's what you want I think the reason is over-production in this one, that's why the guitars are a bit distant like lots of reverb and eq-ing. When I record my guitars (usually through s/pdif and rarely from the effects loop, when I use the G-system) are almost as they should be, non lots of post production is necessary, except sometimes a little eq maybe to let the some frequencies breath more. The rest (multiband eq-compression-limiter) are on the final mix.
I am not an expert, so I'm waiting to hear some other members' feedback and advice.
Keep rocking, mate! You have the heart!
