Currently I run a passive bass into a Markbass Compressore which is on all the time. I'd like to add some distortion on top. Could I run bass > compressore > rolls sx21 crossover > high: turbo rat (for now) > low: nothing > Boss LS-2 and put the mixed signal back to the amp? Would I need a boost or buffer (a la JimmyM's recent thread) before the Rolls sx21, or is it worth trying as I describe it? Will there be any phase issues with an active mixer pedal? I thank you for your expertise!
