Ive been going direct with the PODxt with great results. My sound is great through the PA, but I have no amp on stage for stage volume to keep up with a drummer and guitarist. The monitors help but i'd still like to have a backline amp on stage. Using an amp modeler with a regular bass amp has always had bad results, as it should be. So im thinking using a PA cab (ie JBL 2way 15 cab, perhaps adding a sub as well.) and poweramp for my backline amp. What problems do you think I may run into with this setup? how does a 2way PA cab differ from a regular bass cab as far as how it funtions? Any ideas on if this is a good or bad idea let me know thanks.
