Ive got a Peavey 412 tvx that I've been playing out of with a Ampeg pf500 head. The cabinet sounds fine and the volume is definitely there to keep up with a loud drummer and two screaming guitars but the thing is heavy as s#!+ So I have been wondering what my next move should be. I would like to keep my impedance at 4ohm so I can get the most out of the head I've already got. What are your thoughts/preferences? We play heavy rock but not super heavy although I'm generally tuned down a step and a half. I've thought about Ampeg 410s or maybe two 210 cabs Daisy chained vertically. Any recommendations? Music stores around here are not plentiful. Not trying to spend an arm and a leg but want to get something I won't regret and will keep up with a full band that gets loud.
