I currently own a 1210 and want to add another cabinet for increased low end, NOT increased volume. That said, you would probably think I should add the 1212, but one advantage I see to getting another 1210 is that I can place both cabs on the ground facing different directions and that the tone out of both will be identical. 1210/1210 or 1210/1212...I can't make up my mind. What would you choose and why? Thanks!
