One thing is cool, though, about a big amph through a 4x12 cab is the WHUMP. Turn that amph up, stand in front of the cab, and hit a power chord. The feeling when the sound hits you in the chest (the WHUMP, that's the best way I can describe it) is incredible. There really is nothing like it.

Of course, there really is nothing like tinnitus either, so I like my smaller amph.
