that's a matter of opinion.
it's pretty hard to carry a cab on a bus that will (IMO) sound better and have equal volume to an ampeg SVT/810 cab.
With all due respect, i very much disagree with that comment, i use a gk mb800 , neo 2/2x12 and i have had several players that own that very rig tell me that it is just as loud and while it does sound a little different sounds almost just as good. I know that you ampeg svt 8x10 guys will go to your grave denying the fact that there can be gear that may be better but its a new day with new gear that is very good! and my mb8 weighs 4.9 pounds and doesnt need $300 worth of 6550's every year something that an svt owner can never say!
