GK has a bi-amp with 700 watts for the lows and 50 watts for the highs. 50 watts seems awful lightweight for the mid to high end to me. Any comments on that or on this amp? What about just getting a power amp with 500-700 watts per side, adding an active crossover, and using my Line 6 Bass Pod for a preamp? I play stock 4-string Fender Jazz basses. I play medium volume classic rock gigs, but sometimes need pretty high volume for playing outside. I am using an SWR Workingman 4004 amp through Aguilar GS1-12 cab and an Avatar neo 2-10 cab. Though rated at 400 watts into 4 ohms the SWR does not get very loud, even using both cabs. (My ancient Peavy TNT130 with 15 inch BlackWidow gets much louder). The Aguilar has response down to 41 hertz so I was thinking of using it for the lows and the Avatar for mids-highs. Any advice will be greatly appreciated, even if it involves starting over to build a decent rig!
