Here is Misha from Periphery talking about how to get rid of some of the inherent "flub" (e.g. unwanted exaggerated bass boominess that kills the tightness of your gain) of a PEAVEY 5150 style head.
This head and it's children are used non stop for METAL. Sadly, as with all tube amps, the bottom end saturates at a much lower point than mids and highs and you get "flub". Boofy/boomy bass that has no "tightness" at all. The easy fix, use a Tube Screamer! Or something similar which actually reduced the amount of bass getting to the amp.
So it's like using a parametric eq in a way, which we've also talkd about. The bass frequencies tend to "bunch up" under high gain so making them behave is crucial. Unless you are playing SLUDGE/DOOM.
