Heres the deal. I currently have a GK amp with a SVT 4x10HE and a SVT 1x15. When playing live, I would rather not have a single cab mic'd, being that the two cabs produce substancially different sounds (I don't count on many sound guys giving me two mics). and I don't want to do any direct outs either before the amp or On the amp, being that some of my sound and effects will be bypassed. By the way, my setup is very complicated, miles away from any standard Bass-Straight-To-Amp-To-Speakers setup. I was wondering, how good is directing out from the speaker line? Especially with a simple, no-tone-changing direct box like the Rolls DB25?
