I've had the Bass Cub and the Flightcase. Like them overall, but eventually found they just didn't have enough 'ooomph'. Maybe with the two C4 cabs, it'll punch a bit more.
I recently picked up a used AER Amp Three here on TB. OMG! That thing kills! 200W and (2) 8" speakers. Sounds better than some much bigger rigs I've owned. Not cheap though. :-/
I'm not familiar with AER amps I'll have to check that out!
