I'm floored by this one. I tested my real 5150 head vs the PVH Block model and it's just silly how close it is. No tone matching. All amp settings are pretty much identical except the presence on my head is at 7 to match the model at zero. I turned up the supply sag on the model to "feel" more like my amp when palm muting, but didn't touch any other advanced parameters.
The real amp and model switch halfway through the first section. I randomly switched around several times on the second section. Sounds pretty dang close to me.
Those do sound pretty dang close. Whichever one is first in the first half seems to have a little bit more of a throaty tonality, a little more fullness and warmth on the lowend. The second has a bit more clarify and tightness, but still some nice thumps on the palm mutes.
You find the Presence has to be dialed to 0 on the Axe to match your amp though?
