I just added an Egnater Armageddon Profile to Rig Exchange. I used a lonely SM57 (with a reflexion filter) on the K100 side of an Egnater Armageddon 4x12. This amp slays!
Enjoy!
EDIT:
I just updated the profile using a different mic'ing technique and slightly different settings. It is called "Armageddon FT" and should be close to the top of the Rig Exchange. One of the only amp profiles I've come across where I have to dial DOWN the definition.
