Nice jam!
I really do wonder about my setup. I try presets like these (was able to get the settings off the vid, and the right IR), and it is SOOOOO bright on my studio monitors, using my PRS Cu24 with a WCR Godwood bridge pickup. Brutal. If I roll the tone knob off to about 3, I can tolerate it, but otherwise it is just shrill. Only thing I couldn't see from the vid was where the highs are rolled off on the cab IR, so I'm betting you just leave it stock at 20k.
I also noticed I had to turn the input drive down relative to this video to get something other than just fuzz, and this isn't a really hot pickup. Maybe you rolled off the volume knob (without a treble bleed?) for that main riff, then dimed it for the solo?
Really good tones in this amp, for sure, but...I wonder.
