Cool man, post them on custom tone.

I like that tone a lot so I just had to play with it, and then I started tweaking. :-)

Here's what I came up with - I think you'll like the results - the EQ is relatively the same but you get more clarity from the high end, and the upper mids sound less noisy to me.  Let me know what you think.

These are all dual tones.  I used the Treadplate 4x12 with SM57 on axis on channel 1 to dial in the upper mids and treble.  They all use the XXL cab for channel 2 but I vary the mics.  The first link uses a SM57 on axis; the last 2 use the 409 Dynamic.  The last two patches are EQ'ed slightly differently - I basically removed a common fizzy spot on the last one, hence the "-fizz" in the name.

I used the Classic Distortion instead of Tube Screamer, just because I like it more.  I couldn't get the dual noise gate thing to happen (DSP limit), but it's not going to have much effect on the tone when you don't use your overdrive pedal to add compression.  I only use dual gates when I have a compressor or if I turn up the drive a little on my overdrive pedal.

And I couldn't fit the delay/compressor.  If you want to add compression, turn up the drive on the Classic Distortion.  If you want delay, change the first EQ (it has the least effect on the tone) to the delay you want.
