I'm considering the following setup, but I'm a reall rookie so I could use as much help as one can give. I'd like to run a GK 700RB-II through an Avatar NEO B212 or B210, but I've read that there is an issue with stacking non-GK cabs with this head. Something about bi-amping. Is this correct? I'm not sure what, if any, cabs I would add in the future, but I want to have some flexibility. Maybe a NEO 410 or 210 at some point down the road. And if I do decide to stack at some point I assume that getting an 8 ohm B212 is the way to go right now. Please enlighten me. Thanks.
