Alright, let's say I have a combo that I really like the sound of. Can I take the line out or efx loop send, plug that into a power amp, then from the power amp to a cab? My goal would be to use the full power of the combo to drive it's own speaker, but send the same eq'd signal out to the power amp and the other cab. Is this feasible? Or does the power amp need a hotter signal?
