OK - I appreciate all of the "less gain is better" comments - but to be clear:

I just want stupid gain levels for playing solo in the music room, just for $#!ts and giggles because insane gain.

You might should just buy an ENGL Fireball or Powerball

OK, that AMT box is evil. And I mean that in a good way...

Agreed. I have to say even the more vintage high gain marketed SS11 is capable of some straight up wicked metal grind.
