The automation of EQ is not a "rule" it`s just common production knowledge that you are opening yourself up for a world of difficulty and trouble if you use it for mix purposes.
It can be done creatively, I use mid sweeping a fair bit when constructing atmospherics.
See above, there`s nothing to say you can`t do anything "in the mix"
Doesn`t mean it won`t sound shite though.
75% of my music making time is spent trying shit out just for the sake of it, so don`t paint me into a hypochritical corner buddy.
I`m just talking from experience that`s all.
As for guitars, it`s been tried and tried and tried.
So it`s nothing new.
It`s very old in fact, trying to meld heavy guitar and techno.
It rarely rarely works, but then, it `s mainly to do with how techno works spacially.
Guitars work well with drum and bass though. But the general spacial construction of drum and bass is different. It`s percussively fairly sparse to begin with in general.
