I've been looking at Ampeg SVT Pro stuff, at the suggestion of my drummer, but I'm having a hard time finding info on the pros and cons of micro vs. traditional, all tube vs. hybrid, etc. I've got a 4ohm 8X10 cab and the band I'm in plays sludgy heavy stoney baloney. We do occasional shows at club-sized rooms and bars and such. Apologies if this has already been covered a zillion times. And thanks for any forthcoming suggestions.
