The G12T-75s seemed to impede the personality of my 2204. They are great for modern crunch and open back systems because they are a little bassy but a little flat on the midrange.
I like Weber Blue Dogs and Greenbacks for that amp. I have a v30 but I'm not crazy about it. It does not have as much life as the others. That seems contrary to popular opinion though. I will sell mine cheap if you want it.
