Based on the sample sound clip provided by OP, the first thing i noticed is that it doesn't sound a lot different than when i first load a preset from the naked preset pack, when i am using my EC1000 with EMGs - i always have to tweak, but i have always had to tweak guitar amps, even tube amps.
I find that the same tweaks do much the same things for either - try tipping low/high ratio before going into amp with low shelf or cut from parametric EQ block - roll off bass knob, boost treble knob a bit - decrease master volume to tighten up any flab - add presence and a sliver of treble cap boost to taste - after the cab (or IR) low shelf boost EQ. block to regain low end if cab requires it. From there it is all about the environment where the sound is coming from, in other words, the room, or the room (or lack of) you create in a recording mix or headphones.
