Hey there all, I just found myself a trace-elliot ah500x bi-amped head from the late eighties. Pretty cool looking head,with a built in black light. It's biamped with two 250 watt amps and can be run 500 watt bridged as well. Previously I have just used combos for bass, though I have had a few guitar stacks. Should I use the bi-amping and get say a 410 and a 15, or go with the bridged and get an 810 or 610?
