mesas are NOT TIGHT. They are not designed to be tight, and probably never will be, they do sound tight at bedroom levels but once you bring up the volume it all goes to spongy. Bogner Uberschall is decent, but thats a $%load of cash to dish out. Engl savage isnt as tight as the power ball ;)
my knowledge in order of crazy tightness
Engl Powerball (tightest you will ever get)
Engl Fireball (a powerball with half the wattage and less channels)
VHT Pitbull
Engl savage (i dont know if it should be before the pitbull though...)
peavey 5150
Engl SE
throw any of these on a VHT, mesa, or orange cabinet, and you'll have a tight ass monster.
