I have recently made a few mistakes. I was playing through an ampeg 8x10 and an ampeg SVT pro 4 head, but didnt really like the sound i was getting. So i decied to but a new rig, in haste, I bought a SWR SM500 head, an SWR Goliath Senior 6X10 cab and an SWR Son of Bertha 1x15 cab. It sounded great in the store but when i got it home and started playing with my band it just didnt have the same punch and volume that it had in the store. So i guess what Im getting at is....does anyone know if there is a way to run the SM500 with an external power amp? any advise would be greatly appreacated.
