hey man, several problems i'm seeing in your patch.
1) Noise Gate is set up high. The standard "Noise Gate" is not just a gate, it's a "noise reducer" and can suck tone when Threshold is as high as you have it. Use a Hard Gate for a true gate without tone suck.
2) Screamer settings seem crazy. With the EMG-81 I assume you have in the bridge (which I'm assuming you're using for your rhythm tone), you should have a high output, bright tone. From the clips I listened to, I would have guessed you had a Fred or something dark as your pickup. Your Screamer settings are making the patch way too dark. I would leave Bass at 50% or lower it maybe to 40%. But really, the Bass/Treble settings don't even exist on a real Screamer. The Tone knob is what everyone uses to get their ideal filter tone. Start with Bass, Treble, and Tone at 50% and move tone up and down until things start sounding where you want them.
3) Everything has too much gain. You shouldn't need that much at all. Usually people use a Screamer or boost pedal in front with 0% to 15% Drive - that keeps the pedal from adding distortion, just a bit of compression. It acts as a filter/mids-boost, which causes your amp to distort differently - tighter and more focused. I suggest starting with 0% Drive, 100% output, and then toying with the amp Drive starting at 50%.
4) Input Settings Guitar+Aux means you're getting the noise of Aux into your tone. Set Input 1 to just guitar. Set Input 2 to Variax.
5) Why do you want to use Dual Amps? I'm not a fan of this - I find they interfere with each other more than anything. I see you have them panned hard left/right. I would focus on one good mono tone first. Then make another. If you want them on the same track, record them separately. True double-tracking always sounds better than panning 2 tones hard left/right.
6) Why are you using the "pre" models? If you're trying for a direct tone, you will probably prefer the "full" models - they have more bite and aggression to my ear.
I cover all of these topics in the guide I linked you to. At the top and bottom of the page are links back to the table of contents. Go there, and you can access everything in-depth. Or just read through the "quick guide" page. It's labeled II. Quick Guide.
