So I'm looking to make an upgrade/switch to a vertical stacked 210 config. I have a Mesa Walkabout and a Markbass TTE-500. The cabs I currently have are a Carvin BRX10.4 and 10.2. Since both are 4ohms, I can't run them together with the Markbass. So in my research, I've narrowed it down to Ampeg PF-210HE or Mesa Traditional Powerhouse 210. Does anyone have side-by-side comparisons with these? I like that the Ampeg is less expensive, but if the Mesa would be a better fit, it's within my budget.
