I REALLY like the Orange sound - a Thunderverb 60 (or 200) through an Orange 4x12 with V30s in my opinion is pure tone bliss. That said, I tried an Orange 4x12 with V30s with my old mark iva and was totally disappointed. I only had about 15 minutes to play around, but in that time I wasn't able to find setting that sounded good. So before you buy one, try it with your head to see if you like it.
