Thanks for the feedback chaps, slightly updated version here.

Is it the guitars, or the mix as a whole that is a bit sharp?
The guitarists wanted a very crunchy sound (not to mention a load of bottom end, once they had done their eq I was not to touch it, I tried to explain that the higher eq such as 16khz and 20khz need rolling off, but they said they are needed for higher notes.
But anyway I went and made a few small changes (without them knowing)

.
Rolled off the guitars low end, as they were treading in the bass guitars territory, talking as low as 80hz 100hz etc (guitarists for ya eh? Lol).
Rolled off the high end slightly on guitars, boost the bass guitars mids a tad to break through the mix.
Recording and mixing isn't as easy as people think, trying to eq everything so that it has it's own place in the mix is not a walk in the park, especially when you got guitarist who want 'their sound'.
