I play rock/funk/country all with the same band. My pre/power head has been a love hate thing for a while due to both it's clipping problem and it's weight. I'm using different cabs at different venues. I have a SWR Goliath III (4ohm) and an Ampeg 810e for big outdoor stuff. Anyone pair up a GK1001-RB with an Ampeg 810? Will it power the cab nicely?
