But don't I need like 1000 watts and 8 15 inch drivers?
no... unless you are famous and playing stadia...
if you are like the rest of us and play smaller venues
check out the Roland Cube Bass series.
I like the CB-60XT which has an XLR out... so if you play a larger venue
you can plug it into the mains, and it sounds HUGE... *grins

This tiny little bass amp has a lot more punch than you'd think, mostly because it's
modern technology and includes the "ports' on the bottom, which increase the low end
and authority of the sound. I swear by mine, but then again, I don't have to stand next
to an insane drummer and try to find a place in the 'mix."
