Is this a bright or a dark instrument?
For a bright instrument, I always recommend the Juggernauts for heavy tones, particularly for drop tuning, cleans, tight rhythms, and phat leads.
But the A-Bomb is pretty awesome for a raw and pissed off tone. I have some samples that I scratched together quickly. I can send them to you VIA PM if you would like.
Granted, the amp I was using is no where near as modern sounding as a Bogner Ubershall but the character of the pickups comes through nonetheless.
For pickups, I bet you'd like Juggernauts with the Mark V 25. that brighter and more mid focused amp likes being bludgeoned with a low mid focused pickup.
The A-Bomb would likely work really well with the Uberschall. Probably would get along with a Mark V 25 but I plugged my A-Bomb equipped Les Paul into a Mark V and I prefer my juggernaut equipped super strat. That being said, the A-Bomb sounds great into a modern voiced high gain head like a Recto or even something more current. (In this case, ReVv Generator 120 or 7 - 40)
